Sint-Pieterskerk, Parish church in Kortessem, Belgium.

Sint-Pieterskerk is a three-aisled cruciform basilica with a partly built-in west tower of five stages, its walls of grey-brown rubble stone with flint and quartzite and lighter stone trim. The tower carries a steep dark pyramidal roof with a small cross and round-arched windows in its upper stages; the nave has a dark slate gable roof, round-arched side windows and a large pointed window on the left end facade, and a low grey annex with a dark roof runs along the tower's right base.

Construction started in the 1000s with the Romanesque nave built from 1026 to 1038, and the west tower was added during the 1100s. These two building phases show how the church began as a prayer space and was gradually expanded.

The interior holds paintings from the 1700s showing Saint John and the Baptism of Jesus, along with various saint statues and marble altars. These artworks shaped how worshippers experienced their faith over the centuries.

The church stands at Kerkplein 1, with the west tower partly built into the nave and low side aisles running forward to its front. Enter through the marlstone round arch into the nave; the transept and choir lie beyond. The churchyard holds 16th- to 18th-century gravestones, so allow time to walk it.

The graveyard around the church holds tombstones from several centuries, including markers for owners of the nearby Kasteel Printhagen. These graves link the place of worship to the area's aristocratic history.
