A historical post-Camaldolese monastery is located on the peninsula on the lake Wigry and is the most precious architectural landmark in Wigry National Park.

Before the 13th century one of the tribes of Yotvingians lived in the village of Wigry region, but they were almost completely exterminated due to the aggressive attacks of neighboring groups. Later there was a royal hunting lodge here, which belonged to Lithuanian Princes. At that time was still an island.

In 1667, the Polish King Jan Kazimierz granted the island with the buildings, the lake and parts of the adjacent forest to the Camaldolese order. The monks inhabited the island in 1668 and established their headquarters there. They rebuilt the hunting manor and erected some outbuildings. In 1671 great fire devoured wooden buildings. The Camaldolese decided to build a brick monastery. A church, 12 isolated monasteries, a refectory, Chancellor's chapel, clock tower, curtal friar’s house and outbuildings were built. The last building of the monastery complex i.e. a church, was built in 1694-1745. A mill and a brewery were also built. The island was fortified and connected to the mainland via a causeway. The monks carried out settlement activities. They were bringing settlers from the nearby Mazowsze region and East Prussia, founding villages and farms, tar and ore manufactures, iron, copper and glass smelters, lime furnaces. In 1715 the monks founded the city of Suwałki. Because of such activities the Wigry monastery became the wealthiest monastery in Europe. In 18th c. the Camaldolese owned the city of Suwalki, 11 farms, 56 villages, 10-20 big lakes, 6 mills, 404 beehives, a lime-burning furnace and a brick kiln, numerous distilleries, breweries, ore, tar and ash manufactures and almost 8,500 subjects. In 1796 all monastery's goods were confiscated by the Prussian government and the monks were displaced.

During World War I the monastery was destroyed. During the interwar period it was almost completely rebuilt, but then during World War II it was ruined once again. After the war, the monastery was renovated from war damages. Until now, the Church of the Virgin Mary, the isolated monasteries, the refectory, the Chancellor's chapel, the clock tower, and the curtal friar’s house have been rebuilt.
