St. Lucius, Romanesque church in Werden, Germany.

St. Lucius is a Romanesque church in Werden, a district of Essen. Its massive, fortress-like west tower is fronted by an almost apsidal entrance hall, and two small towers flank the choir bay above the eastern yoke. The northern choir wall keeps its original three-tiered structure with a niche-like triforium, and early Romanesque wall paintings survive between the arcade and the clerestory.

Construction began in 995 under Abbot Werinbert, and Archbishop Anno II of Cologne consecrated the church in 1063. Around 1100 it received lower side aisles separated from the nave by a Rhenish alternating support system. Secularized in 1803, it served from 1811 as a grain store and later as housing; partitions were removed from 1957 and the restored church was reconsecrated in 1965.

The church is still used mainly for children's and school services. Its name refers to Saint Lucius, and the building was a branch church of the Benedictine monastery of Werden. In 1985 the interior, including the beamed ceiling, was partly repainted after designs by the Hattingen artist Egon Stratmann, drawing on historical colour records.

The church stands in Werden, south of Essen's city centre, near the former Benedictine monastery. It is a branch church, so opening hours vary; services today are mainly for children and school groups, and checking times before visiting is advised.

After secularization in 1803, the building served as a grain storage facility and residential dwelling before returning to church use in 1965. This transformation remains visible in the architecture and tells of the varied history experienced by many German churches.
