St. Martinus, Medieval church in Dom-Esch, Euskirchen, Germany

St. Martinus is a single-nave medieval church in Dom-Esch, a district of Euskirchen. The nave measures 6.30 m wide and 19 m long, with a west tower and an east choir ending in a 5/8 polygonal apse. Pointed-arch windows light the three-bay nave, which has a wooden ribbed vault while the choir has a stone one.

St. Martinus grew from the chapel of a fortified estate sold to the Cologne Cathedral Chapter in 1273 and held by it until secularisation in 1803. The chapter probably extended the main and side choirs in the 14th century. In the 16th century, when the church had become dilapidated, the side aisles were likely demolished and their stone used to wall up the arcades; buttresses were added to the north wall and a sacristy built on the south wall.

The church's name comes from its medieval dedication to Saint Martin, and the main altar holds a figure of the saint beneath the coat of arms of the Cologne Cathedral Chapter. The old bells are named after saints: St. Maria (1414), St. Martinus (1429) and St. Johannes (1517).

The church interior is accessible to visitors, particularly during religious services and open days. Check the community's opening hours and event calendar before your visit.

The tower's lower-level light slits were enlarged in 1935 for two figurative windows by Friedrich Lauten, then walled back up during a tower restoration and fitted with abstract glass painting; Paul Weigmann made a new St. Martin window above the sacristy door in 1992.
