Sint Pieterskerk, Leerbeek

The Church of Our Lady is located in a rural area. The current church was built between 1619 and 1635 on the remains of a 12th-century church. This church was linked to The Priory of the Order of H. Augustine which was founded in 1182. The church's roofs, facades, stained glass windows, vaults and interior were restored in 2013-2014. In 2023 the restoration of interior elements started.

The abbey of Forest, founded in 1106, lived from its glory days until the 15th century when the abbey was emptied of its inhabitants as a result of wars and epidemics. It was only in the 18th century that the abbey rose again and was rebuilt in its present form. However, this resurrection was short-lived because the French Revolution suppressed the religious community of the abbey and sold the building.

The church of Saint-Denis is a religious building whose oldest foundations date back to the 11th century, around the time of the founding of the village of Forest. The present building, which includes the sanctuary dedicated to Saint Alène, dates from the 13th century and is in Gothic style. The bell tower was raised by two floors in the 18th century. In 1925-1926, an important restoration of the ensemble was carried out by Chrétien Veraart, restoring to the building a luminosity that it had lost.
