The mosque at Karaköy village, near Bolu, was built in 1562-63 as a Friday mosque by the mother of Mehmet Bey, son of Musa Pasha, as its inscriptions show. It is rectangular, laid in rubble stone, with a flat wooden ceiling carried on four wooden posts in two rows, and an open porch on the north also carried on wooden posts.
Two things are worth looking at closely. The main door is marble with a low arch, and its wooden leaves are worked in the kundekari technique; above it is a tiled inscription in thuluth script. The mosque is known to have had two tiled inscriptions, but one of them no longer survives. Inside, four piers of square section on the north carry the wooden gallery. The mihrab has five sides with muqarnas, and the minbar is plain wood. The windows run in two rows: the lower ones have pointed-arched pediments and wooden frames, the upper ones pointed arches with plaster tracery. The eaves are corbelled brick.
