Founded in 1258, the St. Agnes Beguinage of Sint-Truiden is one of thirteen Flemish beguinages inscribed on the UNESCO World Heritage List. It includes a Gothic church, now a museum of religious art, in a rectangular courtyard bordered by centuries-old houses that were once occupied by semi-monastic women known as Beguines. Outside this main rectangle is an infirmary-farm complex with monumental gate and barn.
