"It’s easy to assume that any castle in the Middle East was built by a Crusader, but the one at Ajloun is a notable exception. Constructed in 1184 by Izz ad-Din Usama bin Munqidh, general and nephew of the great Saladin, it commands a terrific hilltop position above the town of Ajloun, daring anyone to invade its walls. The castle itself is relatively modest but excellently preserved, which is perhaps a surprise given its turbulent history—it was sacked by the Mongols, rebuilt by the Mamelukes, garrisoned by the Ottomans, and repeatedly damaged by earthquakes. There is a small museum, but the atmospheric stonework and tremendous views from the ramparts are the real highlight of any visit here."
