Gdańsk Travel Guide: What to Know Before You Go

WWII started here on September 1, 1939. In 1980, the movement that ended the Cold War began here too. Gdańsk earns attention on historical grounds alone. The beautiful Old Town you walk through was almost entirely rebuilt from rubble after 1945, a fact that makes it more interesting, not less.

Understanding Gdańsk: the German-Polish city

For most of modern history, this city was called Danzig. The name alone captures the tension. Germanic, Baltic, and Polish histories converge here in ways that explain both the destruction of 1945 and the city’s unlikely second life.

The city grew wealthy as a Hanseatic League port from the 13th century. Baltic amber, Prussian grain, and Flemish merchants passed through here. By the 16th century, Gdańsk was one of the most prosperous trading cities in northern Europe. The architecture of Long Street and Long Market reflects that wealth, or rather, the memory of it.

After World War I, the Treaty of Versailles created the Free City of Danzig, neither German nor Polish, governed by the League of Nations. It was an unstable arrangement. On September 1, 1939, Germany resolved the ambiguity with force.

Allied bombing and street-by-street Soviet-German fighting in 1945 destroyed roughly 90% of the historic center. After the war, the city became Polish. Polish architects, working from old paintings and photographs, rebuilt the medieval and Baroque streetscapes over several decades. The reconstruction was meticulous. It was also entirely deliberate, a political and cultural act of reclaiming the city as Polish. Standing on Długa Street now, knowing this, changes what you see.

The Long Lane and Old Town

Długi Targ (Long Market) and the Neptune fountain

Długa Street and Długi Targ, Long Lane and Long Market, form the main axis of the Old Town. The street runs east-west, flanked by tall, narrow merchant houses in shades of ochre, terracotta, and olive. The proportions recall Amsterdam and Bruges. That’s not accidental; those are the cities whose merchants competed here.

At the western end of Długi Targ, in front of Artus Court, stands the Fontanna Neptuna, the Neptune Fountain. It was built in 1633, destroyed in 1945, and rebuilt in the 1950s. Neptune raises his trident over an elaborate bronze base. It marks the center of civic life as it has, in various forms, for nearly 400 years.

The Green Gate and the Golden Gate

The Golden Gate marks the western entrance to Długa Street. It was completed in 1614, rebuilt post-WWII, and served as the triumphal entry point for Polish royalty visiting the city. Four female allegorical figures stand above the arch: Peace, Freedom, Prosperity, and Fame.

The Green Gate at the eastern end served a similar ceremonial function. Polish kings used it as a temporary royal residence. Walk through both. The route between them was the route of state.

St. Mary’s Church

St. Mary’s is one of the largest brick churches in the world. The numbers make more sense inside the building. The nave is 66 metres long, 27 metres wide, and 29 metres high. The building can hold 25,000 people.

The interior is mostly bare, stripped of most decoration in the Reformation, then damaged and looted during WWII. What remains has weight. The astronomical clock from 1464 is the most remarkable object inside. It shows the time, the day, the month, the lunar phase, and the position of the sun in the zodiac. Adam and Eve figures strike the hours.

Climb the tower. The 400-step ascent delivers a rooftop view over the Old Town reconstruction and the waterfront. On a clear day, the Gulf of Gdańsk extends to the horizon. The climb earns the view.

Mariacka Street and amber

Mariacka Street runs between St. Mary’s Church and the Motława River. Gothic townhouses with perron terraces front amber jewelry shops along both sides. The street is pleasant. The amber question requires more care.

Gdańsk is the amber capital of the Baltic. Most of the world’s amber comes from the seabed and shoreline of the Baltic region. The city has sold amber for centuries. What’s sold on Mariacka Street ranges from genuine Baltic amber to dyed, treated, or synthetic pieces priced as if they were real.

How to identify quality: look for pieces with visible inclusions: air bubbles, ancient plant material, occasionally insects. Real amber is lightweight, warm to the touch, and floats in saturated saltwater. Quality jewelry carries certification from the International Amber Association. Buy from shops displaying that certification. Avoid stalls where prices seem too low for the size of the piece.

Where WWII began: Westerplatte

On September 1, 1939, at 4:48 in the morning, the German battleship Schleswig-Holstein opened fire on a small Polish military garrison at Westerplatte, a narrow peninsula at the entrance to Gdańsk harbour, at the mouth of the Dead Vistula (Martwa Wisła). These were the first shots of World War II. Those 182 Polish soldiers held out for seven days against repeated German assault before surrendering.

The peninsula is now a park and monument. A large socialist-realist monument from 1966 stands at the site. The ruins of the garrison guardhouse are preserved. The space is appropriately solemn. The actual scale of the garrison (how small it was) helps explain both the tactical situation and the meaning of the seven-day resistance.

Getting there: bus 106 from the city center takes about 30 minutes. Boat tours from the Motława waterfront also run to Westerplatte in summer. The boat route approaches the peninsula from the water, giving a clearer sense of the geography.

The European Solidarity Centre

This is the best museum in Gdańsk. The building, opened in 2014, occupies the site of the former Lenin Shipyard where the Solidarity trade union was founded in August 1980. The exterior is shaped like a ship’s hull: rusting Corten steel, deliberately industrial. It looks nothing like a conventional museum. That’s the point.

The permanent exhibition covers the 1980 strikes and the broader Solidarity movement in rigorous, moving detail. The 21 Demands signed by the communist government on August 31, 1980 are displayed on original plywood boards. Lech Wałęsa’s chunky red pen, used to sign that agreement, is in a case nearby.

Why it matters beyond Poland: Solidarity was the first successful legal trade union in the Soviet bloc. Its eventual success, under Wałęsa’s leadership and with the organizational support of the Catholic Church, accelerated the collapse of communist governments across Eastern Europe. The museum makes that arc clear.

Even visitors with limited interest in 20th-century political history find the exhibition powerful. Allow two hours. The gift shop stocks excellent archival publications.

Museum of the Second World War

The Museum of the Second World War opened in 2017 near the main train station. The collection is vast: the underground space descends four levels and covers the war’s global scope and civilian experience at a scale almost no other museum attempts.

The political context: under the previous Polish government, the museum faced intense pressure and a leadership change critics argued was motivated by the desire for a more nationalist-leaning exhibition. The original directors were replaced. After the 2023 change of government a new director was appointed in 2024 and some of those changes were reversed. It remains worth visiting (the collection is genuinely extraordinary), but the political background is worth knowing.

Allow three to four hours. Book tickets in advance. Summer queues can be long.

The Motława waterfront

The Motława River runs through the eastern edge of the Old Town. The waterfront district, the former warehouse and crane area, has been converted into restaurants and hotels. Granary Island (Wyspa Spichrzów), connected by drawbridges, holds many of the newer hospitality developments.

The Old Crane (Żuraw) stands on the western bank. Built in the 15th century, it’s the largest surviving medieval port crane in Europe. It lifted cargo and masts for ships. The interior is a branch of the Maritime Museum. Even from the outside, the crane’s wooden frame and scale justify a stop.

Boat tours depart from the waterfront for Westerplatte in summer. The journey takes about 45 minutes each way. The boat passes still-active industrial shipyard areas, which gives a sense of what the working port once was.

The Tri-City: Sopot and Gdynia

Gdańsk, Sopot, and Gdynia run together along the Gulf of Gdańsk coast, connected by SKM commuter rail every few minutes. Each has a distinct character.

Sopot was built as a Baltic resort town in the late 19th century. Art Nouveau villas, spa hotels, and a 511-metre wooden pier, the longest wooden pier in Europe, define its character. Sopot fills with visitors in July and August. The main pedestrian street, Monte Cassino, connects the train station to the pier and is lined with cafés and bars. The beach is wide, the sand fine, the water cold even in August.

Gdynia is different. It was built largely in the 1920s and 1930s as a modern Polish port, constructed to reduce dependence on the then-autonomous Gdańsk. The architecture is early Modernist: white ships-prow buildings, geometric facades, functional maritime aesthetics. The restored WWII destroyer ORP Błyskawica, now a museum ship of the Naval Museum, is excellent and often overlooked.

A day covering all three cities is achievable and genuinely interesting. Start in Gdynia, work south through Sopot, and end in Gdańsk, or reverse the order.

Day trips from Gdańsk

Malbork Castle is 60km southeast of Gdańsk, about one hour by train. It is the largest castle in the world by land area and one of the best-preserved examples of Teutonic Knight architecture anywhere. The red brick scale is staggering. It was heavily damaged in WWII and has been under continual restoration since. Allow four to five hours. The train runs directly from Gdańsk Główny station.

The Hel Peninsula is a narrow strip of land curling 35km into the Gulf of Gdańsk. Reachable by train from Gdańsk Główny, the ride takes over two hours to the tip at Hel town. Beaches are wide on the Gulf side and steep on the open sea side. The peninsula has a seal rescue station. It’s a straightforward summer day trip.

Getting there and around

By air: Gdańsk Lech Wałęsa Airport (GDN) receives direct flights from most major European cities. The bus or train into the city takes about 25 minutes.

By train: Warsaw to Gdańsk takes approximately 3 hours on PKP Intercity express service. Trains run frequently throughout the day. Book in advance for the best prices.

Cruise port: Gdańsk is a regular Baltic cruise port. Ships dock at the Nowy Port or Westerplatte area. The waterfront and Old Town are reachable by shuttle or taxi. The center is walkable once you arrive.

Getting around the city: The Old Town and main attractions are compact and walkable. Tram and bus lines cover the wider city. The SKM commuter rail handles Tri-City connections.

When to go

June through August is the best period for Gdańsk and the Baltic coast. Sopot and the beaches are viable. Outdoor cafés are open. July brings the Dominikański Fair, one of Poland’s oldest outdoor markets, running in Gdańsk since 1260. It takes over the streets of the Old Town for about three weeks, from late July to mid-August. Worth planning around, or planning around avoiding, depending on your preference for crowds.

September is a strong alternative: cooler temperatures, fewer visitors, and the main sights are fully open. May and early June are underrated, still cool but uncrowded.

Winter is atmospheric and quiet. St. Mary’s Church holds a major Christmas concert series. The Christmas market at Długi Targ is smaller than those in German cities but well-organized. Expect cold, occasional snow, and a more local character to the city.

Frequently asked questions

How many days do you need in Gdańsk? Two full days cover the Old Town, Westerplatte, St. Mary’s, and one of the major museums. Three days adds the European Solidarity Centre, the Tri-City, or Malbork Castle. A fourth day allows the Hel Peninsula in summer.

Is the Old Town actually old? Not in construction terms. The historic center was about 90% destroyed in WWII and rebuilt from scratch using pre-war paintings, photographs, and architectural records. The buildings are mostly 1950s and 1960s construction with historical facades. The street plan and proportions are accurate to the originals. Whether it counts as “old” depends on your definition, but the deliberateness of the reconstruction is part of what makes the city interesting.

What currency does Poland use? Poland uses the Polish Zloty (PLN). Gdańsk has plenty of ATMs and cards are accepted most places. Avoid currency exchange booths at the airport or train station: rates are poor. ATMs at major banks offer considerably better rates.

How do I get from Gdańsk to Krakow? By train, direct PKP Intercity express services take approximately 5 to 6 hours. The flight takes just over an hour from GDN to KRK.

What was the Solidarity movement? In August 1980, workers at the Gdańsk Lenin Shipyard went on strike. They were protesting food price increases and the dismissal of a crane operator. The strike spread. The government eventually negotiated with the strike committee, led by electrician Lech Wałęsa, and recognized the right to independent trade unions. That agreement, the August Accords, was the first crack in Soviet-bloc state power. It led, eventually, to the end of the Cold War. The European Solidarity Centre tells this story well.

Is Westerplatte worth the trip? Yes, but go with context. The site itself (ruined guardhouse, monument, quiet peninsula) doesn’t explain its significance without background knowledge. Read about the September 1939 attack before you go, or take a guided boat tour whose narration covers the history on the way there.

How does Gdańsk compare to Krakow or Warsaw? Krakow has more intact historical architecture and more tourist infrastructure. Warsaw is the capital, with grander museums and a harder-edged rebuilt Old Town. Gdańsk is more specific in its historical character: the combination of Hanseatic merchant wealth, German-Polish tension, WWII origins, and Solidarity is unique. It’s a stronger choice for visitors interested in 20th-century history.

Is Gdańsk safe? Yes. Gdańsk is one of Poland’s safest cities. The main tourist areas are well-maintained and comfortable. Standard precautions apply around train stations and at night in less-visited areas.
