Segorbe Castle was an Arabian alcázar (palace or castle). Very little remains of the original alcázar, but the large complex was a residence of lords, dukes and kings for over a millennium.
.After the Muslim king of Valencia, Zayd Abu Zayd, converted to Christianity and declared himself an ally and vassal of King James I of Aragon, he ceded the fortress to James in 1229 and became governor general of Valencia on his behalf. The castle became a sanctuary for Zayd Abu Zayd himself when he was killed by Dynamil Zayyan until James captured the castle in 1245, and placed Abu Zayd in command of an army to assist in the retaking of Valencia.
The castle had a peak in the 14th and 15th centuries, culminating in the holding of General Courts by King Martin of Aragon, who had made the city his residence.
In 1784, urban expansion of Segorbe beyond the original medieval fortifications required further construction, and new walls were built. After the works were completed, the new walls had eight gates.
References:Doune Castle was originally built in the thirteenth century, then probably damaged in the Scottish Wars of Independence, before being rebuilt in its present form in the late 14th century by Robert Stewart, Duke of Albany (c. 1340–1420), the son of King Robert II of Scots, and Regent of Scotland from 1388 until his death. Duke Robert"s stronghold has survived relatively unchanged and complete, and the whole castle was traditionally thought of as the result of a single period of construction at this time. The castle passed to the crown in 1425, when Albany"s son was executed, and was used as a royal hunting lodge and dower house.
In the later 16th century, Doune became the property of the Earls of Moray. The castle saw military action during the Wars of the Three Kingdoms and Glencairn"s rising in the mid-17th century, and during the Jacobite risings of the late 17th century and 18th century.
