The usual Top Sites in Istanbul are Blue Mosque, Hagia Sofia, Toptkapi Palace and Bassilica Cistern. It was amazing to see how nicely situated they are -- easy walk from one to the next -- almost like a Disney planner had laid it out. Don't get me wrong -- there's nothing Mickey Mouse about these fabulous historical sites. If you like great architecture -- be prepared to have your breath taken away.
