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:
La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
