The first masonry castle in Dubingiai was constructed by Vytautas, Grand Duke of Lithuania, in 1412-1413 on an island, now apeninsula, in Lake Asveja in order to secure the capital Vilnius from attacks from Livonia. No accounts concerning the architecture of Vytautas' castle have survived. It was acquired by Jerzy Radziwiłł prior to 1508. He constructed a new palace in the Renaissance style in the first half of the 16th century. After the death of Jerzy, his son Mikolaj 'the Red' inherited the property, causing the town nearby to become an important hub for the Reformation in Lithuania. Barbara Radziwiłł spent five months in the castle after her marriage to Sigismund Augustus in 1547. The palace used to be one of the most luxurious residences in the Duchy, lagging not much behind the Royal Palace. Dubingiai Castle was the main seat of the Biržai-Dubingiai line of the Radziwiłł family until the second half of the 17th century, when it was transferred to Biržai Castle.
During the Polish–Swedish wars, the castle was pillaged by armies loyal to the King of Poland and was confiscated fromBogusław Radziwiłł. It returned to the family in the second half of the 17th century. The neglected castle and church gradually fell into ruins. It was sold to Michał Tyszkiewicz in 1808. Today only the foundations and several cellars of the castle and church remain and are being researched.
The masonry Calvinist Church of the Holy Spirit was built in the Renaissance style near the castle by Janusz Radziwiłłprior to 1620 and was intended to be the mausoleum of the Radziwiłł family. The most prominent members of the family were interred there, including Mikołaj 'the Black' Radziwiłł (1565) and his wife Elżbieta Szydłowiecka (1562), Mikołaj 'the Red' Radziwiłł (1584) and Janusz Radziwiłł (1620). Their remains were discovered during archaeologicalexcavations in 2004 and reburied there in 2009.References:
The historic city of Trogir is situated on a small island between the Croatian mainland and the island of Čiovo. Since 1997, it has been included in the UNESCO list of World Heritage Sites for its Venetian architecture.
Trogir has 2300 years of continuous urban tradition. Its culture was created under the influence of the ancient Greeks, and then the Romans, and Venetians. Trogir has a high concentration of palaces, churches, and towers, as well as a fortress on a small island. The orthogonal street plan of this island settlement dates back to the Hellenistic period and it was embellished by successive rulers with many fine public and domestic buildings and fortifications. Its beautiful Romanesque churches are complemented by the outstanding Renaissance and Baroque buildings from the Venetian period.
Trogir is the best-preserved Romanesque-Gothic complex not only in the Adriatic, but in all of Central Europe. Trogir's medieval core, surrounded by walls, comprises a preserved castle and tower and a series of dwellings and palaces from the Romanesque, Gothic, Renaissance and Baroque periods. Trogir's grandest building is the church of St. Lawrence, whose main west portal is a masterpiece by Radovan, and the most significant work of the Romanesque-Gothic style in Croatia.
