Dating to 1559, Tabuk Castle is now a museum, with thorough signage and a room reserved for video presentations. The castle features a ground-floor mosque, an open courtyard and a stairway that ascends to the castle’s second mosque and watchtowers. Outside are cisterns (c AD 650) that captured spring water. The museum has a large collection of antiques and documents dating to the time of the Prophet Muhammad.
There is even a VIP room for international guests, who are served Arabic coffee and dates (museum personnel often coordinate with the restaurant across the street to treat visitors to Saudi hospitality).
