St. Lamberti, Parish church in Gladbeck, Germany.

St. Lamberti is a Roman Catholic parish church in Gladbeck, in the Diocese of Essen, whose red brick tower carries a green copper spire with corner pinnacles. The square shaft has narrow lancet windows, a small white-faced clock, and two statues in niches above a pointed-arch tracery window, with three figures mounted near the base.

The church was founded by a farming settlement; the settlement of Gladbeck took its name from the Gladebeke stream that flowed north of the nave. The parish church was elevated to the rank of a provostry on 1 September 2007. The main altar was consecrated on 23 December 1972 by Bishop Franz Hengsbach of Essen.

The parish is named after Saint Lambertus, bishop of Tongeren-Maastricht, whose feast day on 18 September is still celebrated; the congregation sings "Sankt Lambertus, hoch in Ehren, Unsrer Pfarre Schutzpatron". A market privilege for the Lambertus market was granted on 18 September 1403, and the parish festival is considered the oldest regularly celebrated festival of the area. A relic of the patron is walled into the main altar together with one of the Roman saint Florencia.

The church stands on the western edge of the Vest Recklinghausen, on the boundary between Westphalia and the Rhineland near Oberhausen. The nearest road links run north to Dorsten on the Lippe, south to Essen beyond the Emscher, west to Osterfeld and east to Herten and Recklinghausen. The terrain lies between 60 and 90 metres above sea level.

The church stands on the Gladebeke stream, which gave Gladbeck its name; the water once flowed west past the north side of the nave. The parish's oldest annual festival, the Lambertus market, was granted by privilege on 18 September 1403, and the town still sings "Sankt Lambertus, hoch in Ehren" on the saint's feast day.
