Collegiate Church of Saint Gertrude, Nivelles

The Collegiate Church of Saint Gertrude is a place of worship built in the Romanesque style, featuring rounded arches, thick stone walls, and cylindrical columns. The building extends across multiple levels, with an archaeological basement beneath the main hall and a dedicated chapel for Saint Gertrude.

Construction began in 1001 following the founding of a convent by Saint Gertrude, a medieval religious figure of great influence. Over the centuries, the building underwent various changes and additions while maintaining its core Romanesque features.

The church remains connected to Saint Gertrude, venerated for centuries as a protector of travelers. Visitors can see old artworks and religious objects that show how central this place has been to the community.

The building is open to visitors who can explore it independently or join guided tours of the main areas. Wear comfortable shoes as there are stairs throughout the structure, and check opening hours in advance before planning a visit.

The archaeological basement holds remains of an earlier seventh-century church dedicated to Saint Peter that once stood on the same spot. This hidden level reveals layers of the past that visitors would not otherwise see.
