The church of Plateliai is one of the oldest wooden churches in Lithuania. It was built in 1744 by a group of parishioners and priest Juozapas Vaitkevičius. The church building is in the shape of the cross. A tall roof covers the building, on the corners and the middle of which stand small towers with crosses on them. The external forms are modest: small walls with planks placed vertically and large rectangular windows. Baroque-style main and four side altars, all decorated with columns, carvings and artistic paintings, encased in silver, can be found inside the church. All of the altars were painted white and coated in gold in the 18th century. The pulpit, which was decorated with Rococo ornaments and openwork canopy and a crown, was also repainted. An excellent Rococo-style baptistery and cover still stand in the left chapel. Holy water and sacramental oils are kept in there. Several painted altarpieces with settings („Sts Peter and Paul“, „Jesus of Nazareth“, „St Ann“) from the eighteenth century are of distinguished artistic quality. The end of the nave is the place of the organ, adorned with an elegant arcade and an archaic lodge for the singers. A 10-tone organ, a large drum and an assembly of bells were placed here in the 18th century. The church organ, repaired by Jonas Garalevičius, was set up in the Plateliai Church in 1909.
