The Roman Catholic Church of St. Michael the Archangel in Žemaičių Naumiestis was built in 1782 on the initiative of the town’s landlord, Mykolas Ronikeris.
In 1790, the church was consecrated by Samogitian Bishop Juozapas Koscia and named after St. Michael the Archangel to honor Ronikeris for establishing it.
The church stands on the Vanagiai hillfort, also known as the Green Hill, which is listed in the Register of Archaeological Sites.
It is a wooden church of folk architecture with Neo-Gothic features. It contains valuable religious artworks and sculptures. The church has a cruciform layout with a small tower at the roof crossing.
Inside, there are old paintings, an organ, three altars, a pulpit, two 19th-century iron ornamented crosses, and a wooden sculpture of the Crucified Jesus from the early 20th century.
In the churchyard, a wooden chapel-post with an iron cross was built in 1890. The church also holds three early 20th-century wooden sculptures: Christ at the Pillar, the Crucified Jesus, and Jesus the Nazarene.
In 2006, the parish acquired a new bell.
