The Lviv High Castle is a historic castle located on the top of the Castle Hill of the city of Lviv. It is currently the highest point in the city, above sea level. The castle currently stands in ruins. The High Castle is proximate to the centre of Lviv, formerly being surrounded by a fortification wall. The Castle Hill took its name from the High Castle, which used to be located on the hill from the 13th century to the late 19th century. The castle was a main defensive fort of the city during its existence. As it follows from Rus' Chronicles, the first fortifying structures appeared on the Castle Hill in the time Halych-Volhynia, and were built by Leo I of Halych from wood. It was originally a wood and soil construction, as most others at that time. In 1259 by a request of Burunday Khan they were destroyed, but in 1270 were rebuilt. In 1340, when Lviv was captured by Casimir III of Poland the wooden castle was put under fire. In 1353 it was destroyed again by Lithuanians. A new brick castle appeared on the hill in 1362 by the king Casmimir III. It became the residence of Polish nobles. In 1537, the castle witnessed a rebellion known as Chicken War against Polish kingSigismund I the Old and his wife Bona Sforza. The castle was rebuilt and repaired many times. In the times of Khmelnytsky Uprising it was taken by Cossack forces of Colonel Maksym Kryvonis in October 1648. In 1704, when Lviv was occupied by Swedes the castle was heavily damaged. In 1777, Austrians initiated disassembling of fortifications around the castle. In the 19th century, the then destroyed castle was taken apart and new facilities were built in its place. The fortification was strengthened, trees were planted on the hill's slope, and a park was constructed. On the place where the castle once stood, a Union of Lublin Mound was constructed in 1869, dedicated to the 300-years of the Union of Lublin. Currently, an observation platform is located atop the kurgan. In 1957, a 141-meter tall television tower was constructed on a ridge of the hill. In 2004-2005, there were talks of reconstructing a stone castle on the hill. The project gained some support and opposition. However, at this time, plans for the construction of the castle are not realistic. , a 1966 coming-of-ageautobiographical novel by Polish science fiction writerStanisław Lem refers to the castle.
