Church of Saint Mark, Neoclassical church in Fryštát, Czech Republic.

The Church of Saint Mark is a single-nave classicist building with a three-sided presbytery and a prismatic tower with an onion dome on its west facade. The nave has a flat ceiling, and a four-sided sacristy adjoins the presbytery on the gospel side. The only entrance in use is a side door in the southeast wall, next to which stands the 1864 tombstone of Fryštát priest Josef Plasun.

A wooden Protestant church built in 1569 by Prince Frederick Casimir stood here and was used for funeral services. Catholics took it over in 1654, and the dilapidated building was demolished in 1773. The brick church that replaced it in 1774 was damaged by fire in 1781 and an earthquake in 1786, then rebuilt in 1823–1826 by builder Vavřinec Müller at his own expense.

The church is used ecumenically: services are held by three churches. Its name "Pohřební kostel" (Funeral Church) comes from its origin as a cemetery chapel of the Protestant church built in 1569, where funeral services were held.

The building functions as an active place of worship and is accessible to visitors during opening hours. Those wanting to explore the architecture quietly should visit outside of service times.

The church holds a Baroque tombstone of Benigna Haugwitz von Gaschin from 1674, originally in the churchyard cemetery and now inside the building. A stone cross from 1879 stands by the main entrance, moved there during the 2014 renovation.
