Designed by the most famous architect of the Ottoman Empire, Suleymaniye Mosque Istanbul is a must

Maybe Suleymaniye Mosque's interior won't impress so much but I'm sure its size will make you say "that's huge". It's no doubt Mimar Sinan (the one who build it, considered the most important architect of the Ottoman Empire) wanted to do somenthing breath-taking. The mosque seems to be "more than a mosque", having a hospital, a public kitchen, a public bath and a theological school. The mosque is a must-see, by all means. It's located on Prof Siddik Sami Onar Caddesi.
