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:The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
