St. Martini, Heritage church in Frankleben, Germany.

St. Martini is a village church in Frankleben, a district of Braunsbedra in Saxony-Anhalt. The building has a tower and a simple stone structure typical of Protestant rural churches in this part of Germany.

The lower part of the west tower survives from the 16th century, while the upper section is dated by inscription to 1697. The nave was begun in 1733/1734, probably to plans by Johann Michael Hoppenhaupt I, who was soon replaced by the Dresden architect Wagner. The church stood under the patronage of the von Bose estates Ober-Frankleben and Unter-Frankleben, and since 20 September 2026 it has borne the name Schlosskirche.

St. Martini anchors the center of Frankleben and is where villagers gather for baptisms, weddings, and Sunday services. The tower rises above the rooftops and acts as a natural landmark for anyone moving through the area.

The church sits in the middle of the village and is easy to reach on foot from the surrounding streets. Access to the interior is most reliable during services, as the building may be locked at other times.

The church has been called "Schlosskirche" (palace church) since 20 September 2026, a title recalling its centuries-old link to Frankleben Palace. It stood under the patronage of both estates of the von Bose family, Ober-Frankleben and Unter-Frankleben, whose monuments line the walls beside the galleries.
