Having lost some of its prestige when the French completed the Suez Canal in the 19th century, and struck by a cyclone in 2007, the city has nevertheless retained its scenic dunes and crystal waters. Sur’s most recognisable monument today is the Ras al Haad castle, a gem of Islamic architecture built in the 13th century to protect locals from Christian attacks, and which now serves as a regional political centre. While in town, science aficionados will be lured by the impressive Ras Al Jinz Scientific & Visitor Center, offering modern facilities and apps to discover the local wonders of fauna and flora. Alternatively, for an in-depth discovery of the city’s history, the maritime museum is an excellent choice.
