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 here 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.

In the 1960s the interior got renovated. The gallery and the neo Gothic pulpit were removed. During the restoration work some late Gothic murals were discovered under the ceiling and got restored.
