House of Lusignan
The Château de Lusignan (in Lusignan, Vienne "département", France), of which hardly any traces remain, was the ancestral seat of the House of Lusignan, Poitevin Marcher Lords, who distinguished themselves in the First Crusade and became the royal family of the Kingdom of Jerusalem, the Kingdom of Cyprus and the Armenian Kingdom of Cilicia. Built in the 10th century, it reached its peak four centuries later, decayed and was finally dismantled in the 18th century.
