Aim: The mesjids are small neighborhood house of worships without minbar in which the community fulfills the Daily worshipping requirements. During the historical process in Kayseri, a large number of mesjid with flat roof were built. The aim of this study is to determine the original architectural features of these structures which constitute mesjids without a dome structure, to classify them typologically according to plan schemes and load bearing system properties. In the study, changes and distortions which were formed by today's interventions in some mesjid with no domes were examined. Method: In this study, a field study was conducted depending on determinations made in place and documentation, on a total of 40 mesjid which belong to mesjid architecture without dome. Findings: The plan schemes were divided into two types according to the existence of the last congregation by typological methods and into three types according to the characteristics of the top cover carrier system. In addition, the minbar minarets in almost all mesjid are similar to minbars because of the similarity of the presence of a local ezangahs. In Kayseri, many original mosques, minarets and interior minarets have been transformed into mosques. In addition, uncontrolled interventions such as the reinforced concrete roof overlayed on the bearing walls and the wooden framed roof resting on it have also removed many mosques from their original state. Conclusion: In the Research, it was determined that the plan schemes in Kayseri domeless earth-roofed mesjides have different typologies according to the presence of the last congregation site and the characteristics of the top cover carrier system. Many of these masjids were transformed into a mosque by altering the functionalities of the minbar and minarets as well as the distortion caused by the contradictory interventions. Functional change was due to the idea of providing mosque-specific worship activities, such as Friday and Eid prayer, to the users which increased in parallel with the growth of the neighborhoods of the mosques.
