As you see from the answers, yes there are a lot of graveyards, but you will not really recognize them as graveyards as they look very different from the kind of graveyards other religions have. The Muslim graveyards do not have headstones with names engraved on them. They are basically just a mount of dirt with a rock placed on them. Also Muslims do not go to graveyards and put flowers nor do they go there to pray for the dead.The muslim graveyard is a place were they rest the body, and this body does not have a soul anymore, so just an empty shell.
