Kasaba Mahmutbey Mosque Mahmutbey Mosque, found in the village of Kasaba, which lies about 18 miles (11 kilometers) east of Kastamonu, stands as an important cultural landmark within Kastamonu Province. Although the village is small today, it historically played a key role as a notable settlement in the region. Mahmutbey Mosque, commissioned by Mahmut Bey of the Candarid dynasty in 1366, is remarkable for being constructed entirely without cement (except for the mihrab) and without any metal components in its roofing. It is popularly known as the "mosque without nails" or "Çivisiz camii" in Turkish. The mosque has a rectangular layout and is among the earliest examples of wood-columned and wooden-roofed mosques in Anatolia. Its exterior walls are built from finely cut stone, while inside, four wooden pillars uphold the ceiling decorated with plant-based dyed motifs called "kalem işi." The mosque’s entrance portal was once an exquisite work of art, now preserved in the Kastamonu Ethnography Museum, with a faithful replica placed at the original location. On April 15, 2014, Mahmutbey Mosque was placed on UNESCO’s tentative list of World Heritage Sites under the cultural category. Later, in 2023, it was officially inscribed on the UNESCO World Heritage List along with four other historic mosques in Turkey.
