Situated in Gaza's Daraj quarter, the popular Mosque of Said Hashim was built in 1850 under orders from Ottoman Sultan Abdul Majeed, using masonry from mosques and older buildings destroyed by Napoleon's troops. Its name refers to the Prophet Mohammed's great-grandfather, Hashim, a prominent merchant who died as he was passing through Gaza, and whose tomb rests in the mosque's northwestern corner.
This is one of Gaza's biggest and most attractive mosques, and, like the Great Mosque, you should be able to look in when there's no prayer in session.
