On the picture before this one you can read a notice "Havlucular Sokak Int. 101". This street I could locate asking Google Maps to show me Havlucular Sokak, Bursa, Turkey. It turns out to be somewhat Northeast of the Ulu Camii, some 500-600 meters from there. I am not aware if the building still exists, not having passed it last time around. But the street should be easy to find if you print the Google map.
And indeed this building is one of the better ones and of a type I love.
