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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
