The Château Moncade is a ruined castle in the commune of Orthez in the Pyrénées-Atlantiques département. Construction of the castle was started in 1242 by the Gaston VII, Viscount of Béarn (the keep, known as the tour de Moncade) taking advantage of the absence of Edward III. When the King returned, Gaston was imprisoned and had to swear allegiance before being released. He subsequently reneged.
It was the residence of the Kings of Béarn when their capital was Orthez. Standing on top of a hill above the town, it afforded views of the surrounding county over a radius of more than 30 kilometres. The central tower was surrounded by high curtain walls and moats up to 15 metres deep. Entry was by a drawbridge.
In the 14th century, Gaston Phébus, Count of Foix, altered it between 1368 and 1375. The castle was burned during the Wars of Religion in 1569. It was sold during the French Revolution to dismantlers who largely demolished the curtain wall.
The only remains are the keep (in a good state of preservation), the moats (in course of restoration) and remnants of the curtain wall. The castle is open to the public (paying) and contains, among other items, a model of the site.
References:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
