For the ease of following through the narratives of places I visited, I also put the map below. It was definitely not an easy task to pick what to saw and visited since there were just so many beautiful places with so little time we had (classic problem of traveler).
The famous Blue Mosque (Sultan Ahmed Mosque)
So, after we had a breakfast, we directly went to Blue Mosque (although it wasn’t open yet). Basically we just walked around the mosque complex and admired the magnificent of each of its edges and curves.
Believe it or not, we were quite lucky to get a Hotel that literally 5 minutes walk from Blue Mosque, and guess what ?! Our breakfast area has the direct view to Blue Mosque. We stayed at Star Holiday Hostel in Sultanahmed and it was probably the best choice for us if not for all traveler who means to travel around the complex. (it also helps that the bell boy is strikingly handsome ;) ). The room price is reasonable as well.
Topkapi Palace was built during Ottoman Empire and remained a Sultan Palace for about 400 years until the Sultans started to prefer staying in Dolmabahce Palace around 17th century. The palace is very wide and it’s a place we can get lost within. There are several courtyard and many other buildings. It was a home to 4000 people. Each building has a unique architecture and the interior is astonishing. The Ottoman art and design pretty much stamped in every murals, interiors, patterns, and choose of color.
Hagia Sophia (Aya Sofya)
The attractive things inside the Basilica cistern were the lights emanating from each of the column that makes them look beautiful in the dark. Also, the upside-down medusa pillar. There were two columns inside the cistern that use the upside-down and tiled Medusa head as its base.
