St. Gereon, Roman Catholic church in Merheim, Germany

St. Gereon is a Roman Catholic parish church in Merheim, built around 1820 as a single-nave hall church after the old Romanesque church was demolished in 1817. The columns dividing the interior into a main nave and two side aisles were added only in 1907. The tower dates from 1822; its octagonal spire of 1849 was replaced at the start of World War II by a blunt pyramidal roof. The baroque high altar stands in the apse.

Frankish gravestones found at Merheim point to a parish church existing there since the 8th century. Villages across the parish sent their residents to Sunday Mass in Merheim until the 19th century, and surrounding paths still carry the name Kirchweg. The old Romanesque church was demolished in 1817, and the present church was begun around 1820.

The church houses a collection of apostle statues from the 1840s, positioned along the columns of the central nave. These sculptures shape the appearance of the interior and reflect the artistic decoration of the sacred space.

The church stands slightly apart from Merheim's centre, surrounded by meadows and fields, with gravestones and monuments of the former cemetery around it. The parish house with the pastoral office and the parish and youth centre are next door. The tower's green cross with weathervane by Walter Prinz reaches 4.60 m.

The tower's tall octagonal spire, added in 1849, was replaced at the start of World War II by a blunt pyramidal roof because of a nearby airfield. The tower now carries a green cross with a weathercock by Walter Prinz, 4.60 m high.
