I'm not one for grand mosques. They're all basically the same - big, once opulent, built more to glorify the builder, rather than who the builder prays to.
Houses, I can spend hours in. And the House of the Cretan Woman (now known as the Gayer Anderson Museum), next to the Ibn Tulun Mosque is a real gem.
Actually, it's two 17th century houses joined together. Used to belong to a couple of wealthy ladies, one of whom was from Crete.
When the brits were here, a major by the name of Gayer Anderson (an unfortunate first name in the schoolyard, I'm sure) took over the place, restored it, and filled it with quite a bit of stuff - kitsch, stolen artifacts, and lots of paintings of himself.
Everything in this place - from furniture, to cushions, to books - is over a hundred years old, and in really good shape.
I read somewhere that part of the Bond film The Spy Who Loved Me was also shot here. Couldn't tell you what part, though.
Look it up.
