The Château de Blain was originally constructed by order of Alan IV, Duke of Brittany, around 1108. The fortress passed by marriage to the Clisson family in 1225. Following Olivier I de Clisson's revolt against the Duke, the castle was razed in 1260.
Olivier I's son, Olivier II obtained permission from the Duke to rebuild the castle. The Clissons progressively enlarged the castle during the 14th century. In 1407, the castle became the property of the House of Rohan. Louis, duc de Rohan is buried here. During the French Wars of Religion, the castle was besieged and set on fire in 1591 during the fighting between the Duke of Mercœur and Jean de Montauban, the knight De Goust. It was restored by Catherine de Parthenay, who installed herself there with her children. In 1628, Henri II de Rohan having become the leader of the Protestant princes, Cardinal Richelieu ordered the dismantling of the castle which thus lost its military role.
The castle suffered further serious damage during the French Revolution. It was pillaged and burnt, along with the Rohan family archives. It served as a barracks and later as a prison. It passed through the hands of several proprietors, including Marie Bonaparte in 1918. These owners remodelled the north wing (known as the Logis du Roy) and the Mill Tower (la tour du moulin).
The South West Tower and the Drawbridge Tower with the buildings on either side form the entrance to the castle. Along with the Constable's Tower (tour du Connétable), the two towers in the south east and the monumental entrance on the south facade of the logis du Roi, they date from before the 17th century. Together with the remains of the towers and the fortifications linking them, these have been classified as a monument historique by the French Ministry of Culture. The north wing of the logis du Roi was remodelled in the 19th century. The castle is home to a fresco centre and an ancient printshop. It has been listed since 1977 as a monument historique by the French Ministry of Culture.References:
The Palace of the Kings of Navarre of Olite was one of the seats of the Court of the Kingdom of Navarre, since the reign of Charles III 'the Noble' until its conquest by Castile (1512). The fortification is both castle and palace, although it was built more like a courtier building to fulfill a military function.
On an ancient Roman fortification was built during the reign of Sancho VII of Navarre (13th century) and extended by his successors Theobald I and Theobald II, which the latter was is installed in the palace in 1269 and there he signed the consent letter for the wedding of Blanche of Artois with his brother Henry I of Navarre, who in turn, Henry I since 1271 used the palace as a temporary residence. This ancient area is known as the Old Palace.
Then the palace was housing the Navarrese court from the 14th until 16th centuries, Since the annexation (integration) of the kingdom of Navarre for the Crown of Castile in 1512 began the decline of the castle and therefore its practically neglect and deterioration. At that time it was an official residence for the Viceroys of Navarre.
In 1813 Navarrese guerrilla fighter Espoz y Mina during the Napoleonic French Invasion burned the palace with the aim to French could not make forts in it, which almost brought in ruin. It is since 1937 when architects José and Javier Yarnoz Larrosa began the rehabilitation (except the non-damaged church) for the castle palace, giving it back its original appearance and see today. The restoration work was completed in 1967 and was paid by the Foral Government of Navarre.
