The St. Agnes Beguinage in Sint-Truiden was built in the mid-13th century. Beguinage is an architectural complex which was created to house beguines: lay religious women who lived in community without taking vows or retiring from the world. In its heyday there were more than 200 beguines. Most houses were built during the 17th or 18th century when the original half-timbered houses were replaced due great fire.
The Romanesque-Gothic church of Beguinage has an impressive series of murals and paintings on pillars dating from the 13th to the 17th century. They witness unique religious belief in the Middle Ages. The organ (1644) is considered the most homogeneous and most complete in Belgium.
The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
