It had already suffered significant damage to the choir's roof and windows in February of that year, but the latter air-raid razed all but the base of the tower and some remnants of the nave's walls.

[3][4] The principal entrance is on the western side of the building while the choir, of Peter and Paul, faces east with the Passion altar constructed in 1420.

The baptismal font was constructed in 1502; it is mounted on three lion masks and has an impressive cover made in 1550 by Hans Meissner of Brunswick.

The unique features of the font are the embossed figure of St. Lambert (wearing shoes), the patron saint of the Church, and an unusual cruciform.

It was sold in 1715 and replaced by a large Baroque organ, built by Johann Matthias Naumann, a pupil of Arp Schnitger.

[7] The Kantorei (chorale) performs in services, but also concerts of Bach's Passions, masses of the classical period and works by John Rutter, among others.

[6] The church runs a weekly concert series Musik zur Marktzeit (music during market time) on Saturdays.
