Halshany or Holszany Castle is the ruined residence of the Sapieha magnate family and was the seat of the one of the largest land estates in the Grand Duchy of Lithuania. Paweł Stefan Sapieha commissioned its construction and it was erected circa 1610 to replace the older castle, built by of the Holszanski princely family, of whom Sapiehas were descendants and heirs.
Also known as the Black Castle (although it is built of red brick), the residence formerly rivaled Mir Castle as the most elegant private château of the Grand Duchy of Lithuania. The name Black Castle in fact originally applies to a fictional building from a book by Uladzimir Karatkievich, which was loosely based on Halshany Castle.
The castle and the surrounding estates were devastated, robbed and looted, twice: by the invading Swedes troops during the Deluge and during the Great Northern War in 1704. Due to financial stress experienced by the Sapiehas in the wake of the Domestic War and ongoing Great Northern War, the castle had never been fully restored.
Later during the 18th century the castle with its estate diminished by creditors passed to the Żaba family, to be sold to the Korsak family with the estate further diminished by the creditors. The last Polish landlords. the Korsaks, sold, in the last quarter of the 19th century, the castle to a Russian landlord, Gorbanyov, who had the castles' towers pulled down in 1880, but in 1880s, according to the Geographical Dictionary of the Kingdom of Poland, there were still 2 floors occupied with some of the wall paintings visible.
Currently, the castle continues to crumble away. An annual tournament is held near its walls each summer.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
