St. Blasius, Romanesque Revival church in Hamm, Germany

St. Blasius is a three-aisled neo-Romanesque basilica built from 1909 to 1911 by architect Josef Kleesattel on the foundations of a 19th-century classicist church. The exterior features a prominent west tower; inside, the side aisles were painted under Wilhelm Döringer's direction.

A Romanesque church stood in Hamm around 1200; in 1824–1825 Anton Walger built a three-nave Neoclassical parish church on the site. That building became too small, and from 1909 to 1911 Josef Kleesattel erected the present church on its old foundations, consecrated on 22 October 1911 by Cardinal Archbishop Fischer. Badly damaged in World War II, it was restored under architects A. and W. Dickmann so services resumed in 1947; the tower followed later, and a restoration led by architect Dölken ran from 1974 to 1981.

The parish belongs to the parish community of St. Bonifatius since 2011. The church is dedicated to Saint Blaise, and the side aisles were painted under the direction of Wilhelm Döringer. The 1911 consecration was performed by Cardinal Archbishop Fischer, with Mayor Oehler and Count von Spee present.

The building can be visited during regular hours and service times. It's helpful to check local service schedules in advance or contact the church directly about visitor access.

The 1955 organ by Romanus Seifert & Sohn has 34 stops on three manuals and pedal, with cone chests and electric key and stop action. Couplers include I/II as a sub-octave coupler and III/P as a super-octave coupler.
