St. Martin, Parish church in Nienburg/Weser, Germany.

St. Martin is a three-aisled Gothic hall church of brick and Porta sandstone, consecrated in 1441, with a square west tower topped in 1896 by an octagonal copper-clad helm. The nave has three slightly rectangular bays and renewed tracery windows between stepped buttresses, crowned by tall two-tiered gables. The choir, partly sandstone and partly brick, ends in a polygonal apse and has no gables.

St. Martin is documented since the late 13th century, and parts of a cross-shaped basilica from the first half of the 13th century survive in the hall choir. The three-aisled brick hall church with a square west tower, partly of Porta sandstone, was consecrated in 1441. Emanuel Bruno Quaet-Faslem restored it in 1830/31, and in 1896 the tower received its octagonal copper-covered helm.

The twelve small sandstone apostle figures on the altar, carved around 1515/20, are attributed to the Snetlage master from the workshop of the Master of Osnabrück; each has an individual face, posture and even size. Removed from the church in 1830, they were bought back from the art trade in 1987. In the tower hall lies the high-relief grave slab of Count Otto VIII of Hoya (d. 1582) and his wife Agnes, with its two-storey epitaph made in Bremen.

St. Martin is listed as a reliably open church, so visitors can generally count on finding it unlocked. The nave is entered through the renewed portal in the square west tower; the tower hall holds the high-relief tomb slab of Count Otto VIII of Hoya. Look up in the northwest nave bay and on the east wall of the northeast bay for late-Gothic wall paintings restored in 1964.
