The Church of St. Peter and Paul in Plateliai is one of the oldest wooden sanctuaries in Lithuania, built in 1744. Adjacent to it stands a 19th-century wooden belfry. This church has preserved numerous historical artifacts, including valuable paintings, liturgical garments, and utensils. Each artifact, such as a metal chalice, an 18th-century painting "St. Anne," 19th-century artworks "Holy Family," and a procession cross, is recognized as an art monument. Marie Choiseul-Gouffier, one of the last owners of the Plateliai Manor, is buried in the churchyard.
The architecture of the church, although renovated several times, has maintained its authenticity. It traces its origins back to the 15th century when it was established by Stanislovas Kęsgaila, and over time it has become a witness to cultural and historical events. Significant archaeological
findings on Apvalioji Hill indicate that the first sanctuary might have been established here even before the Christianization of Samogitia.
Since 1741, when the energetic pastor Juozapas Vaitkevičius was assigned to the Plateliai church, to the present day, this church has been known for its rich history and architectural uniqueness. The interior is adorned with Baroque altars, exceptional Rococo decorations, and valuable paintings considered miraculous and providing grace to the pilgrims.
The churchyard houses a belfry and intriguing legends about a bell that sank in the lake but is said to emerge every 300 years, adding to the mystery and mysticism of the Plateliai sanctuary. This site, cared for by the clergy and its community, continues its sacred mission, being one of the most important centers of culture and spirituality in Plateliai.
