Mont-Dauphin is one of the many places fortified by Vauban in the second half of the 17th century. Following invasions of Provence by Savoy in 1691 and 1692, Louis XIV dispached Vauban to put the frontier in a better state of defence. In 1692 he came to the Plateau de Mille-Aures, which overlooks both of the invasion routes used by the Savoyards, to fortify it.
The ground in question was on a high hill, roughly four-sided and only readily accessible on one side, another side being steep but passable and the further two sides being cliffs. This meant that the place would only require a short amount of bastioned front, the remainder only requiring a basic wall. The plateau was previously uninhabited, so it was decided that a new town would be built within the fortifications. Plans were made for a front of three arrow headed bastions and two demi-lunes in the north, where the defences were most approachable.
To the south, Vauban planned a trace of smaller bastions, this approach being all but inaccessable. The entrance here was carried over a small demi-lune. Later in the 18th century, the trace of the southern defences was altered, but this demi-lune remained, leaving it oddly skew from the wall. There were serious problems obtaining enough stone for revetting the ditches and ramparts. Thirdly, the threat of invasion from Savoy subsided before the fortifications were completed and the fortress lost its immediate importance. Despite this, Mont-Dauphin was strengthened after French troops suffered a defeat nearby in 1745. For the rest of the century, the barrack buildings multiplied, but some elaborate and extensive plans for extra layers of defence drawn up in 1747 were shelved.
One of the additions that was actually realised is a lunette called the lunette d'arçon, which is an advanced work in the north, but is connected to the fortress by an underground passage. The fortifications at Mont-Dauphin are in very good condition.
In 2008, the place forte of Mont-Dauphin, was listed as a UNESCO World Heritage Site, as part of the 'Fortifications of Vauban' group.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.
