[1]Some mismatched Byzantine things
Near the so-called Goth’s Column in Gülhane Park are some Byzantine remains, decorated by columns assembled from pieces found in the area (41.015114,28.985415). There are records of three possible structures in the region: The Orphanage of St Paul and the churches of St Demetrios and St Menas. The pieces in these photos are probably from the orphanage. The area is lovely in spring when it is an ocean of tulips in a part of the park that is relatively sparsely populated.
