San Miguel Church is built in the Romanesque to Gothic transitional style, apparent in the combination of elements from both styles inside. The richly ornamental northern front is in the Romanesque style and is considered one of the best in Navarre. The most interesting elements are the reliefs on either side of the front, which represent scenes from the Resurrection and the struggle of the Archangel St. Michael. The interior houses a Gothic reredos painted on stucco. It serves as the grave of the marquis of Muruzábal and Eguía. Of note among the sculptures on the reredos is a 17th century San Crispín.
References: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.
