Sint-Truiden Abbey or St. Trudo's Abbey (Dutch: Abdij van Sint-Truiden, Abdij van Sint-Trudo) is a former Benedictine monastery in Sint-Truiden (named after Saint Trudo) in the province of Limburg Belgium. The abbey was founded in the 7th century and was one of the oldest and most powerful in the Low Countries. The town of Sint-Truiden grew up around it. The great Romanesque abbey church, dedicated to Saint Remaclus and Saint Quintin, was demolished in 1798, four years after the suppression of the abbey.
