The present church is made of bricks, it has one nave and is oriented. It has a brick belfry, also from 1803, standing next to it. The oldest monument in the church in Tarnawa is the 16th century Gothic-Renaissance baptismal font and a tombstone with a bas-relief of Joachim Lubomirski – member of the Lubomirski family, which used to own these lands. Interestingly, Joachim Lubomirski was the first of the family to convert to Calvinism, and in 1560 he turned the church in Tarnawa to a Calvinist temple, where he was finally buried.
