The Premonstratensian abbey in Middelburg was founded in 1127. Most of the buildings were destroyed by fire in 1492 and 1568. Today there are two adjacent churches, Koorkerk and Nieuwe Kerk. The Nieuwe Kerk dates from the 16th century, with the nearby Koorkerk abbey church dating from the 14th century. The octagonal tower, known as Lange Jan (Tall John), also originally dating from the 14th century but unfortunately has burned down several times. Its 91m height dominates the city but is difficult to photograph because of the surrounding buildings.
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.
