In 1828 Alanta was bought by the nobleman Pac-Pomarnackis, whose family built the Alanta mansion from masonry and stones in the second half of the 19th century. Here the owners had accumulated a valuable art collection: paintings, furniture and oriental porcelain. In the 20th century, between the wars, the manor was bought by the Minister of National Defense of Lithuania, Balys Sližys. During the Soviet era, this was a collective farm office, a cinema and gymnasium, a school, and a library. During the time of the new freedom, the manor spaces were used for public education.
Currently, the permanent art gallery of V. Žukas with the author's paintings, drawings, collages, and ceramics operates on the first floor of the Alanta manor homestead. Three more halls are dedicated to mobile exhibitions - exhibitions of contemporary Lithuanian artists are held. In 2017 facsimile drawings by Rembrandt were exhibited here.
On the second floor of the manor there is a museum of Blessed T. Matulionis, who came from the Alanta region. The martyr bishop's letters from Soviet prisons, exiles, and other documents are on display. Among the most valuable relics of the T. Matulionis museum are the bishop’s glasses, a clock, a razor, and a rosary that he brought back the Solovki concentration camp, a small altar he carved in exile in Mordovia, cut out Christmas toys, and a bamboo stick, which the bishop used to lean on during the Soviet exile in Birštonas and Šeduva (1956-1962). Some of the museum's exhibits were received as gifts from the parishes of Varakļāni and Gaigavala in Latvia, where priest T. Matulionis served at the beginning of the 20th century. On the walls of the T. Matulionis Museum - 30 enlarged photos of the bishop's life.
