Edirnekapı Hill is highest hill of Istanbul with 76 meters. Edirne Gate that gave this hill its name, is the e most important gate after Golden Gate.
The gate took its name as it is situated on the way to the province of Edirne. Some Byzantium emperors used this gate to go on expedition also Ottoman sultas were entering to Istanbul from this gate after they gird on with holy sword in Eyüp.
Ottoman sultans who succeeded to his throne, entered the city from this gate. It was a sort of gate of ceremony.
There are stairs to climb on the walls extending from Tekfur Palace to Edirne Gate. You can walk on the walls and make a history journey that goes back thousands of years.
I am recommending especially you climb on the bastion which is high 25 meters. The panorama of Istanbul seems perfectly from here.
The mini list of historical buildings which needs to be seen in Edirnekapı.
Mihrimah Sultan Mosque and Complex, built by Mimar Sinan in 16th century; Khora Museum is famous with Byzantine mosaics; Tekfur Palace which is only part left from Bleherna Palace which is a Byzantine Palace.
