St Lamberti Church, Lutheran church in Oldenburg, Germany

St Lamberti Church is a red-brick church in central Oldenburg with a neo-Gothic exterior and a classicist rotunda interior. Its steep dark roof carries four green copper corner spires and a central spire reaching 86 metres, with a small green dome between the central and right spires. Tall, narrow windows pierce the brick walls.

A first church, probably a single-nave Romanesque building, stood between the castle and the settlement; its founding is dated between 1180 and 1200. A parish priest is documented in 1237, and around 1400 the church was rebuilt as a late Gothic hall church. After parts collapsed in 1791, Joseph Bernhard Winck converted the interior into a classicist rotunda from 1795. The west tower and main spire followed in 1873–1875, and four corner towers with red brick cladding in 1885–1887.

The church functions as the primary preaching location for the bishop of the Evangelical Lutheran Church in Oldenburg. Worshippers gather here regularly for services and religious events.

The building is centrally located in Oldenburg, positioned between the old Rathaus to the north and Schloss Oldenburg to the southeast. Its central location makes it easily accessible on foot and simple to include in a walking tour.

The free-standing bell tower was demolished in 1813 to enlarge the market square, leaving the church towerless; the poet Heinrich Heine mocked it by comparing it to a theatre. The west tower and the 86-metre main tower were added only in 1873–1875, and the four corner towers followed in 1885–1887.
