Parish Church of St. Peter and Paul and St. Demetrios Martyr in Hanna was built in the first half of the eighteenth century as Uniate Orthodox Church, founded by the Radziwill FAmily. In the 20s of the twentieth century it was changed to Catholic Church.
The Church reminds Orthodox Church, since there was preserved characteristic tripartite division of the Eastern rite: the chancel, nave and women's gallery. Adjacent to the sanctuary are: the vesrty and treasury, to the aisle-side chapel dedicated to Christ crucified while to the women's gallery-vestibule. Feature of the Church is a cross from the seventeenth century (on the triumphal arch). The interior of the Church covers interesting polychrome painted on canvas and glued to the wall. On the axis of the Church stands a three-storey bell tower, built at the same time as the Church.
