The Château de Montluc, named after its famous owner Blaise de Monluc, is located in Estillac, in the French department of Lot-et-Garonne. Built in the 13th century, it was expanded in the 16th century in a Renaissance style by the Mondenard family. Blaise de Monluc inherited it in 1544 and undertook major works, including the addition of defensive bastions inspired by Italian fortifications. He also planned a funerary chapel for himself. The castle was modified to withstand the religious wars but was partially demolished in 1793. Blaise de Monluc lived here to write his commentaries but died in 1577, leaving the estate to his grandson. Over the centuries, the castle changed hands and was classified as a historic monument in 1958. Its architecture features a trapezoidal plan with an almost triangular interior courtyard.
Inverness Castle sits on a cliff overlooking the River Ness. The red sandstone structure evident today was built in 1836 by architect William Burn. It is built on the site of an 11th-century (c. 1057) defensive structure. Today, it houses Inverness Sheriff Court.
The castle is said to have been built by Máel Coluim III of Scotland, after he had razed to the ground the castle in which Macbeth of Scotland according to much later tradition, murdered Máel Coluim"s father Donnchad I of Scotland, and which stood on a hill around 1 km to the north-east.
The first Inverness Castle was partially destroyed by King Robert I of Scotland and a replacement castle was sacked in the 15th century by the Clan Donald during the Siege of Inverness (1429). The castle was occupied during the Raid on Ross in 1491.
In 1548 another castle with tower was completed by George Gordon, 4th Earl of Huntly (1514–1562). He was constable of the castle until 1562.
