Maybe they're obvious, maybe not, but I’ll start by mentioning some of the main tourist attractions:
The Blue Mosque (Sultanahmet), Suleymanie Mosque, the New Mosque, and many others - all beautiful and everyone can enter freely as long as they take off their shoes and cover their legs and shoulders. Entrance during praying times might be restricted. The Turkish word for mosque is 'camii'.
