St. Martinus, Catholic church in Hattersheim am Main, Germany

St. Martinus is a Romanesque Revival church built by Ludwig Becker in 1914–15, with Jugendstil touches. Its cream-coloured walls and grey slate roofs end at the left in a polygonal apse with a round window above three tall arched windows. A lower side aisle runs along the right, and a square tower with a clock and steep slate spire stands at the right end.

A medieval chapel stood here, documented in 1313 when Hattersheim became an independent parish. In 1747 a Baroque church dedicated to Martin of Tours replaced it, with a ridge turret. Ludwig Becker largely demolished it for the present building, completed in 1915, keeping part of the old structure as a transept and baptismal chapel, along with the west windows, entrance and turret.

The parish is named after Martin of Tours, and the church keeps a 15th-century statue of Mary and a pulpit from around 1800 that were carried over from the Baroque church of 1747. The building also serves as a venue of the Rheingau Musik Festival; the vocal ensemble Voces8 performed here on 14 July 2022.

St. Martinus stands on the highest point of Hattersheim's centre, at about 100 metres, so the tower is visible from much of the old town. The choir faces west and the tower is offset to the north-east; the entrance kept from the Baroque church is on the west side. The building is an active parish church, so visits fit around services.

The 15th-century statue of Mary and the pulpit from around 1800 survived the 1915 rebuilding and were kept in the new church. The old Baroque choir was reused as the transept, now a baptismal chapel, and its ridge turret still sits on the roof. The organ, built by Eduard Wagenbach in 1936 with 36 stops, three manuals and pedal, suits Romantic-era music.
