I wrote about the five must see sites in the Historic Peninsula in my previous post that can be found here. All of those locations are within a few minutes walking distance from each other. However there are five other locations I highly recommend checking out that aren't in the same area but are just as important and deemed "must see". These five are the Rüstem Pasha Mosque, Grand Bazaar, Spice Bazaar, Dolmabahçe Palace, and Galata Tower...

It’s super convenient that a good chunk of the major must-see sights in Istanbul are all within close proximity of each other in the Historic Peninsula. This makes it easier for travelers who prefer to explore on their own, because they can walk to the next location without having to worry too much about transportation. Topkapi Palace, Hagia Sophia, the Blue Mosque, Basilica Cistern, and the Hippodrome of Constantine are all within a few minutes walk from each other. They’re the big must-see sites in Istanbul and all of them are impressive and unique in their own right...
