The Kasaba Mosque is located near the central square of Genisea, behind the Mustafa Pasha Mosque, which dates to the era of Sultan Murad IV. Constructed in the 15th or 16th century, the mosque incorporates elements of folk architecture and artistry reminiscent of local tobacco warehouse designs. Inside the mosque, the mihrab (a niche indicating the direction of Mecca) is made of local stone with intricate relief decorations, while the monumental entrance from the vestibule to the main prayer hall is also crafted from the same material. An inscription, now preserved in the Mustafa Pasha Mosque, indicates that the present building was reconstructed following a fire in 1873, replacing an earlier structure. The mosque's most striking feature is its high minaret, built with local isodomic and chipped stones, standing as a testament to the enduring architectural heritage of the region.
