The Green Gate (Brama Zielona) is one of the city's most notable tourist attractions. With the Golden Gate and the Highland Gate, the Green Gate spans the Long Market and Long Street, together comprising the Royal Route. The Green Gate was clearly inspired by the Antwerp City Hall. It was built 1568-1571 as the formal residence of Poland's monarchs. It is a masterpiece by Regnier (or Reiner van Amsterdam), an Amsterdam architect, and reflects Flemish architectural influence in Gdańsk. Hans Kramer likely participated in its construction.
On 11-20 February 1646 the future Queen of Poland, Marie Louise Gonzaga, was entertained here. In the late 18th century the Nature Society was housed here, but soon moved to the Naturalists' House.
Today the Green Gate houses the National Museum in Gdańsk. Exhibitions, meetings, conferences and shows are held here. The Gdańsk office of former Polish President Lech Wałęsa is located in one of the rooms.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
