St. Mary’s is one of the largest European Brick Gothic buildings, which include castles. Between 1536 and 1572 St. Mary’s Church was used for Roman Catholic and Lutheran services alike. From the 16th century until 1945, when the German Danzig became the Polish Gdańsk, it was the largest Lutheran church in the world. It is 105.5 metres (346 ft) long, and the nave is 66 metres (217 ft) wide. Inside the church is room for 25,000 people. It is an aisled hall church with a transept. It is a co-cathedral in the Roman Catholic Archdiocese of Gdańsk, along with the Oliwa Cathedral.
I wanted to go and see panorama from the tower, because it's known as breathtaking, amazingly beautiful and unique (you can see the town, the sea, the river and so) but we were there too late and it was already closed. Will go there some day again and make photos from the top.
