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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
