After the Roman town of Burdigala (current Bordeaux) ceased to exist, the inhabitants moved away from the river, and the new city centre became what is now the Saint-Pierre district. The first church was built on the premises of the former port in the Middle Ages. The current church dates from the 14th and 15th centuries and was built on the site of ancient Gallo-Roman port. The Flamboyant style appearance survived from the renovation in the 19th century.
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.
