Church of Saint Catherine in Olšová Vrata, Medieval Catholic church in Olšová Vrata, Czech Republic.

The Church of Saint Catherine is a single-nave Gothic church with a three-sided presbytery and a low sacristy attached behind it. The walls are smooth stone with three pairs of round-arched windows, and the shingled roof carries an octagonal Baroque bell turret. A stone portal opens in the west facade, and a low stone wall with buttresses surrounds the former cemetery.

Founded probably in 1246 as a fortified Gothic church with a cemetery, it was first recorded in writing in 1257 among three filial churches of the parish church of St Wenceslas in Loket. It became a parish church in 1352 and kept that role until around 1490, when the new town church of St Michael in Andělská Hora was consecrated and it became filial to it. The present building dates from the late 15th century; a partial Baroque rebuilding and lengthening in 1838–1843 gave it its current form.

The village's German name, Espenthor, appears in the 1676 bell inscription "Ecclesia Espenthor fieri fecit". A carved wooden figure of Saint Catherine from 1822, 0.42 m tall, is dressed in real clothes and signed by Joseph Poellich. The 14 Stations of the Cross paintings on the nave walls date from 1848 and are by the Karlovy Vary painter Josef Reimer.

The building is located in the village of Olšová Vrata and is protected as a cultural monument. Visitors should check opening times beforehand, as it functions as an active place of worship.

The church's 1.15 m carved Gothic statue of Saint Catherine, once the centrepiece of the original main altar until 1842, holds a book in her left hand, leans on a sword with her right and has a wheel at her feet. A 0.9 m late-Gothic statue of Saint Andrew from the early 15th century is now kept in the Karlovy Vary museum.
