Once a church later an imperial mosque, and now a museum Ayasofya is a chronicle of byzantine architecture.The best way to visit this place is with a guided map which gives you the directions and insights to what you are beholding.Purchasing an Istanbul museum card will save you the trouble of standing in long ques waiting to purchase tickets for every museum you want to visit.
