Cemaleddin Ferruh Darülhadisi (Taş Mosque) The Cemaleddin Ferruh Darülhadisi Mosque, located in Çankırı, is regarded as the most important structure from the Seljuk Period. This mosque and its adjoining hospital were built in 1235 by Çankırı Atabeyi (Governor) Cemalettin Ferruh during the rule of the Anatolian Seljuk Sultan, Alaeddin Keykubat I. Unfortunately, the hospital, which was constructed using rubble stone, has been destroyed over time. In 1242, Cemalettin Ferruh commissioned the construction of both a mosque and a Dâr-ûl Hadis (a school dedicated to the study of Hadiths). The mosque is locally referred to as Taş Mescit due to its distinctive architecture and two notable pieces of stone artwork. The first is a "Medical Symbol" featuring two intertwined snakes, which is represented as a figurative stone carving on the mosque and as a sculpture displayed in the Çankırı Museum. The second piece, also housed in the museum, portrays a snake figure entwined in a cup, which is now recognized as a "Pharmacy Symbol". The building also contains a mausoleum with two burial chambers. The burial chamber on the northern façade contains a sarcophagus, while the two-section room on the eastern façade holds five cists. It is believed that mummified corpses, known as cadis, were used during this era, with one of these coffins thought to belong to Cemalettin Ferruh himself, the founder of the structure. His coffin was placed above what is regarded as the main area, or the central chamber. The structure continues to function as a mosque and was utilized as a Mevlevihane (a center for practicing Sufism) for many years, until the founding of the Republic.
