The rotunda (round church) is one of the oldest architectural monuments of the Prekmurje from the middle of the 13th century, named after St. Nicholas. The settlement of Selo (Lak) was first mentioned in written sources in 1340 and 1365 as "seu valle Lak Sancti Nicolai (a Szent Miklós-völgyben)". Today, the rotunda is covered by a round, conical shingle roof with a wooden bell tower. The interior of the church is decorated with frescoes. The first layer of wall paintings was probably made in the first third of the 14th century. Around 1400, large theological scenes were painted on the walls and dome.
