Soğuk Su Mosque is in the Nizamiye quarter of central Giresun and has been a registered cultural property since a decision of 14 February 1986. The exact year it was built is not known. Its inscription says it was raised in the second half of the nineteenth century by a benefactor named Muslim Bey, and that the building was rebuilt in 1895 by the district governor Mahmut Rüştü Bey. The inscription sits above a door that is kept closed, so the most informative thing about the mosque is also the hardest to see.

The mosque is cut stone on a rectangular plan, under a hipped roof of Marseille tiles with narrow eaves. The lower windows are rectangular and the upper ones round-arched. The single-balcony concrete minaret at the northeast is clearly a later addition, entered from outside and of no architectural interest. The gallery, which rested on wooden columns, was pulled down in 1979 and a concrete floor put in instead. The cut-stone mihrab is original to the building; the minbar is new and plain. The mosque is in the centre of town and easy to reach on foot or by car.
