Orthodox church of Exaltation of the Holy Cross in Teplice, Orthodox chapel at Teplice Castle, Czech Republic

The Church of the Exaltation of the Holy Cross is a single-nave stone building with a polygonal apse and buttresses topped by pinnacles. Its northwest facade has a stepped gable with a circular rose window and a stone cross, and a tower with a balustrade and eight pinnacles adjoins the northeast side, next to the square Chapel of St. Anthony.

Volf of Vřesovice, owner of the Teplice estate, built the chapel between 1549 and 1586 in a late Gothic or early Renaissance style, using blocks from the Romanesque basilica of the St. John the Baptist monastery for the tower. A square Chapel of St. Anthony was added in the mid-17th century. In 1798–1806 the exterior and interior were reworked in Romantic Gothic style to plans by Dresden architect Johann August Giessel, and the church was reconsecrated in 1806. Since 1950 it has served permanently for Orthodox worship.

Since 1950 the church has served the Czechoslovak Orthodox Church permanently; the iconostasis before the main altar dates from that same year. Services are held on Sundays and holidays at 10 am, and in 2016 the relics of St. Clare were placed in the side chapel.

Access to the interior is usually limited to service times, so it is best to check visiting hours beforehand. The location sits within the castle grounds and is easy to reach from the main square.

The tower was built with stone blocks taken from the Romanesque basilica of the St. John the Baptist monastery. Volf of Vřesovice was buried here in 1598; his two wives and a granddaughter of the Schönberg family are probably also in the tomb, and possibly his brother Bernard.
