The Grand Mosque was commissioned by Sultan Qaboos and it truly lives up to its name. It is enormous, finely crafted down to the last detail, and an interesting mix of the ancient and ultra-modern. Also, according to the 'mohandis' (engineer) who took me around, there are a lot of steel hooks involved. At virtually every stop, he showed me exactly where the steel hooks fit into the grand scheme of things. You gotta love engineers.
