Nienburg - St. Martin

A document issued by the Diocese of Minden in 1025 refers to this place as "Nyge Borg" (new castle). The settlement got fortified and in 1225 it became a "civitas", when the Counts of Hoya granted the city rights. The major reason for this development was its location at a convenient ford in the Weser River, leading to multiple trade routes radiating from the location.

A Romanesque church existed in the center of Nienburg within the 12th century, already in 1237 a pastor is known here.

This church got replaced by St. Martin a late Gothic brick church. Stones of the predeccessing church got reused in the outer walls of the hall church. The cross shaped basilica got consecrated in 1441 or 1451.

The sandstone base of the dominating tower (73 meters) dates back to the 13th century. The original tower was badly damaged during the Thirty Years' War and was replaced tower after the war. In 1896, this tower got replaced by the neo-Gothic tower.
