Protestant Church Badersleben, Protestant church in Badersleben, Germany.

St. Sixti in Badersleben is a hall church with a massive square west tower topped by a slate-covered spire. The nave, rebuilt in 1719 with a three-sided choir, has large porches on its north and south sides that give the plan a cross shape. Inside, a wooden flat barrel vault with applied ribs spans the space, with a west gallery and a two-storey north gallery.

St. Sixti is first documented as a medieval building; in 1719 it was rebuilt as a Baroque hall church with a three-sided choir closure. The massive square west tower with its pointed spire survives from the late Romanesque original. The parish belongs to the Kirchspiel am Huy in the Kirchenkreis Halberstadt of the Evangelical Church in Central Germany.

The church is dedicated to Saint Sixtus, as the name St. Sixti indicates. Its 1743 altarpiece shows a carved crucifixion group flanked by painted Corinthian columns and large standing figures of Moses, Aaron, Peter and Paul. The stained-glass windows with an Mount of Olives scene were supplied in 1907 by Ferdinand Müller of Quedlinburg.

The church stands in Badersleben, a village in the municipality of Huy in the Harz district of Saxony-Anhalt. The massive square west tower with its pointed spire and the side porches on the north and south walls are the easiest points of orientation from the outside. The interior is entered through the wooden door beneath the tower.

The massive square west tower is the only surviving part of the late-Romanesque building; the rest was rebuilt in 1719 as a Baroque hall church with a three-sided choir. Large porches on the north and south sides give the nave a cross-shaped plan.
