Radziwiłł Palace is a Late Renaissance palace in the Old Town of Vilnius. It had been the second palace of Radziwiłłs by importance in Vilnius and the largest one. It is likely that Mikołaj 'the Black' Radziwiłł"s wooden Vilnius mansion was on the same site, but the current building was constructed by the order of Janusz Radziwiłł from 1635 until 1653, according to the design by Jan Ullrich. The building fell in ruin after the Muscovite invasion 1655-1660 and remain mostly neglected for centuries. It was further devastated during World War I and only the northern wing of the palace survived. Eventually, it was restored in 1980s and a division of the Lithuanian Art Museum is located there today. A part of the palace is still in need of renovation today.
Being the only survived Renaissance palace in Vilnius it has features of the Netherlands Renaissance as well as Manneristic decorations native to the Lithuanian Renaissance architecture. Its original layout and symmetry of structural elements was distinctive to the palaces of the Late French Renaissance resembling that of Château de Fontainebleau and Luxembourg Palace in Paris.References:
Dunluce Castle is a ruined medieval castle located on the edge of a basalt outcropping in County Antrim, and is accessible via a bridge connecting it to the mainland. The castle is surrounded by extremely steep drops on either side, which may have been an important factor to the early Christians and Vikings who were drawn to this place where an early Irish fort once stood.
In the 13th century, Richard Óg de Burgh, 2nd Earl of Ulster, built the first castle at Dunluce. The earliest features of the castle are two large drum towers about 9 metres in diameter on the eastern side, both relics of a stronghold built here by the McQuillans after they became lords of the Route.
The McQuillans were the Lords of Route from the late 13th century until they were displaced by the MacDonnell after losing two major battles against them during the mid- and late-16th century.
Later Dunluce Castle became the home of the chief of the Clan MacDonnell of Antrim and the Clan MacDonald of Dunnyveg from Scotland.
In 1588 the Girona, a galleass from the Spanish Armada, was wrecked in a storm on the rocks nearby. The cannons from the ship were installed in the gatehouses and the rest of the cargo sold, the funds being used to restore the castle.
Dunluce Castle served as the seat of the Earl of Antrim until the impoverishment of the MacDonnells in 1690, following the Battle of the Boyne. Since that time, the castle has deteriorated and parts were scavenged to serve as materials for nearby buildings.
