Church of St. Petka in village Trnava is located in the center of the village, next to the road Raška – Šeremetovica, 10 kilometers from Raška. The church is modest and has simple architecture. After its forms and a limited scale, no dome, with rectangular in plan, with a gabled roof covered with stone slabs, and low height, Trnava church belongs to the rural churches incurred at the time of Turkish ruling. The basis is a single building with a small semicircular apse to the east and at the same time with the narthex built on the west side.

 

It was built of crushed stone vault of cut icicles, and the flagstones are retained only on the roof of the apse. It was built on the foundations of an older church. The church was built and painted in 1579. The preserved frescoes standing figures of saints hierarchs, holy warriors and other saints (St. Sava and St. Simeon), as well as the dominant Great Feasts in the nave and scenes from the life of St. Petka in the narthex, have undoubted stylistic and iconographic value.
