The church of the Transfiguration of the Saviour of Gjirokastër, located in the center of the historical quarter of the Old Bazaar, was part of a more complex architectural system, which developed as a continuation of the eastern side of the Castle. It was a hilltop fortress dominating the western part of the Drinos valley, architectural parts of which date back to before the 12th century. Narrow roads, “cobbled streets”, give access to the site, one of them descending almost vertically from the Castle and the other starting from the central square.
