Trakai Peninsula Castle is one of the castles in Trakai. Built around 1350–1377 by Kęstutis, Duke of Trakai, it was an important defensive structure protecting Trakai and Vilnius, capital of the Grand Duchy of Lithuania, against attacks of the Teutonic Knights. Much of the castle was destroyed in the 17th century. Remaining walls and towers are preserved and protected by the Trakai Historical National Park.
The castle had seven towers connected by a 10 m high wall. The three largest towers, measuring 15 m × 15 m, protected the most vulnerable southwestern flank. A 12–14 m wide moat separated the structure from the town. The castle was attacked in 1382 and 1383 (during the civil war of 1381–1384) and in 1390 (during the civil war of 1389–1392). After the 1422 Treaty of Melno, the castle lost its significance as a defensive structure. It is known that Grand Dukes used it as a residence. Sigismund Kęstutaitis was murdered in the castle on 20 March 1440.
In the 16th century the castle was used as a prison. It was destroyed during the Russo-Polish War (1654–1667) and never rebuilt. The territory was granted to a Dominican cloister in 1678 by Marcjan Aleksander Ogiński, Voivode of Trakai. It was not until the 1770s that the monks eventually built their monastery and church; these buildings are also part of the castle ensemble.
References:The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
