Church in Donji Ajnovci in the vicinity of Kosovska Kamenica, also known as Tamnica (Temnica) was erected in 14th century on the ruins of the earlier Byzantine basilica. Foundation is in the shape of the cross-in-square and probably had a dome. It is built in alternate layers of limestone and brick. As it was it was in ruins for many centuries, only fragments of frescoes have been preserved.
Conservation works were carried out in 1967-68.
