The Beyazıt Paşa Mosque, built in 1414 on initiative of this Grand Vizir of sultan Mehmet I. Its floor plan is that of a reversed T (similar to some early-Ottoman Bursa mosques). The portico (on the north side) is covered by five small domes.

On the picture: The inside decoration of one of those small domes (the one on the left – northeastern - corner, to be precise).
