The Byzantine Monuments Photo Archive is an ongoing project by Koç University Stavros Niarchos Foundation Center for Late Antique and Byzantine Studies (GABAM) to create a digital photographic archive of Byzantine monuments in Istanbul. The core of the archive is made up of monuments found across the Historic Peninsula. Professional photographers have made several visits to each monument to photograph the buildings under the most ideal weather, light and environmental conditions. The archive includes photographs of all visible exterior and interior facades of each monument, and covers a wide range of details from wall paintings to mosaics, and from inscriptions to capitals. Where possible aerial drone photography has been used to document the monument’s location within the current urban environment. The archive will continue to grow as new photographs of the monuments are added.
