St. Remigius, Cultural heritage church in Suderburg, Germany.

St.-Remigius-Kirche consists of a 13th-century round tower of rough grey and brown fieldstone with a tall conical red-tiled roof, attached to a cross-shaped half-timbered hall built in 1752–1753. The nave has red brick lower walls, dark timber framing above, four white-mullioned windows and a wooden door. Inside, pale yellow walls and a flat ceiling frame a baroque pulpit-altar of 1751–1753 with gold detailing, white pews and a brass chandelier.

The round fieldstone tower was built around 1247, when dendrochronology dates an oak beam felled in autumn or winter 1246/1247; it served as a bell tower, not a defensive keep. The old nave was demolished and replaced by the present cross-shaped half-timbered hall, begun on 13 April 1752 to plans by Otto Heinrich von Bonn and consecrated on 1 October 1753, the feast day of St Remigius.

The church is named after Saint Remigius, bishop of Reims (c. 440–533), whose feast day on 1 October was chosen for the consecration in 1753. The name points to a Frankish-era foundation. Inside, a 1303 iron-bound chest was reused as an offering box for donations to the poor; records note it was broken open several times in the 16th century.

The church stands at the edge of Suderburg, with the round fieldstone tower and its red conical roof facing the approach. The tower had to be held up by buttresses even in 1753, and the bells are reached through a window on its west side. The sacristy, added in 1718 by pastor Franz Ernst Hausmann, sits against the church.

A granite millstone, of a type already out of use by the 10th century, is set into the ground beside the tower door; it was found in the church floor during an earlier renovation. The tower's date was settled by dendrochronology: an oak beam built into the fieldstone masonry was felled in autumn or winter 1246/1247, disproving older local claims of a 10th-century origin.
