Eberbach Castle consists of three separate castles situated about 160 metres high above the river Neckar. It is assumed that the front castle was built in the last quarter of the 12th century, the middle castle ca. 1200 and the rear castle in the second quarter of the 13th century. In 1227 King Henry VII was given Eberbach Castle as a fief by the Bishop of Worms. Presumably the castles remained in the possession of the empire until 1330. After that, the castles were pledged to the palsgraves who subsequently used them as a bailiwick of the Electoral Palatinate.
In 1402 Ruprecht III of the Palatinate pledged the town and the castles to the knight Hans von Hirschhorn. In 1403 he obtained permission from the king to demolish and raze the castle, since presumably it was not of any use, but only entailed costs. He thus got rid of competitors for his castles in Hirschhorn and Zwingenberg. By and by the ruins were dismantled and their stones used for building projects in Eberbach, in particular for building walls to fend off game in order to protect the fields lying next to the woodland. Excavations in 1908-09 and 1927-28 exposed the remains of the front and middle castles, and some parts were reconstructed. From 1959-1963 systematic scientific research was carried out, and the rear castle was reconstructed in parts.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.
