Słuszko palace

Slushko Palace in Vilnius, Lithuania is a Baroque palace situated on the left bank of Neris River in the Old Town elderate, former Antakalnis suburb of the city.

The palace was erected in 1690–1700 by voivode of Polock Dominik Słuszko of the Clan of Ostoja, who ordered creating an artificial peninsula on Neris for the purpose of building the palace there. The peninsula was formed from the soil of the leveled down hill separating Antakalnis from the Vilnius Castles. Initially the façades of the palace were unified by a giant order of Ionic pilasters framing huge windows. It is believed that the decoration works of the palace were performed by Michelangelo Palloni and Giovanni Pietro Perti who was the architect of the palace.
