Masyaf Castle (Arabic: قلعة مصياف‎‎) is located in the town of Masyaf in Hama Governorate, Syria, situated in the Orontes Valley, approximately 40 kilometers to the west of Hama. It served to protect the trade routes to cities further inland such as Banyas. The castle itself stands on a platform about 20 meters above the surrounding plain. The citadel became famous as the stronghold from which Rashid ad-Din Sinan, known as the Old Man of the Mountains ruled. He was a leader of the Syrian wing of the Nizari Ismaili Shia Hashshashin sect, also known as the Assassins, and a figure in the history of the Crusades.

The Roman Theatre at Bosra (Arabic: المسرح الروماني ببصرى‎‎) is a large Ancient Roman theatre in Bosra, in the district of Dar'a in south-western Syria.^:143 It was built in either the second quarter^: or the second half of the second century AD,^:143 and is constructed of black basalt. It was built outside the walls of the town, but was later completely enclosed by an Ayyūbid fortress.^:

The theatre is 102 metres across and has seating for about 15,000 people; it is thus among the largest of the Ancient Roman civilisation. It is also one of the best preserved both in Syria and across the Roman empire. It was substantially restored between 1947 and 1970, before which it contained large quantities of sand, which may have helped to protect the interior.
