Until the end of 14th century Verkiai was a property of the Grand Dukes of Lithuania. There was a wooden manor even in 13th century. In 1387 Lithuanian Grand Duke Jogaila, on occasion of accepting Christianity, donated this place to Vilnius' Episcopate. Verkiai served as the permanent summer residence of Vilnius bishops until the end of 18th century.
Verkiai Palace became widely known after bishop Ignacy Jakub Massalski took over it in 1780. He hired two famous architects, Marcin Knackfus and Laurynas Gucevičius, to rebuild the palace in theNeoclassical style. The general plan and maintenance buildings were designed by Marcin Knackfus. The main palace building, the stables and several other buildings were designed by Gucevičius. The building was called 'the Versailles of Vilnius'. The palace had a little theatre, large library, and a small gun museum and was surrounded by a park.
The palace was severely damaged during the Napoleon's invasion of Russia. Eventually, the central building of the palace was pulled down on the order of a new owner, prince Ludwig Wittgenstein, who bought Verkiai in 1839. He also ordered restructuring the other buildings and the east wing office house assumed the role of the palace since the 1840s. It is attested that the first knownphotographs in present-day Lithuania were taken there in 1839, when Karol Podczaszyński made adaguerreotype of the palace which was intended to be rebuilt. The images have not survived.
After World War II, the remaining palace buildings were used as educational institutions and an art museum. Since 1960 the ensemble belongs to the Lithuanian Academy of Sciences Institute of Botany. Verkiai Palace complex is an important cultural and historical landmark in Verkiai Regional Park.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
