Here is a musical motif on an apartment door. This building is on the edge of the Bülbül (nightingale) neighborhood in the Beyğolu district. An earlier post shows a variety of apartment doors in my neighborhood, but none as unusual as this. Here is a larger view of the metalwork on this door:
The Sea of Marmara as seen from the Küçük Ayasofya neighborhood in Fatih. Some of these ships are probably waiting their turn to navigate the challenging Bosphorus. For details about how treacherous this can be, here is information about navigating your yacht through the straights.
This is part of the tile artwork at the Kabataş end of the Kabataş-Taksim funicular. Kabataş is on the Bosphorus which is convenient for its vapur stop.
Here is a fairly close shot of the mosaic detail in one of the domes of the inner narthex at the Chora Church (museum). The original church, built in the 5th century, survived a number of disasters, both natural and man-made. The Byzantine mosaics date from the early 14th century. More about the church here.
This is a close-up of tiles found on the exterior wall of an apartment building on the far edge of the Fatih district, roughly here. This is very close to the northern end of the old city wall.
