The mosques in Turkey, of which the number reached to 87.381 according to the 2018 data (URL-1), are discussed in different political and scientific milieu. Some of these discussions include mosque numbers, mosque design and the role of architects in their design. This article focuses on 234 mosques in the central districts of Van from 1941 until the end of 2013, registered in the Van Müftülük archive. Various statistical data related to printed documents and mosques in the records of the archive were analyzed and interpreted. Data sets that cannot find a place in architectural research, such as records of Müftülük archives, contain important information. The statistical information related to the increase-decrease rates of Van mosques according to years, the builders of mosques, property status of mosques, the mosques with known or unknown designers, can be extracted from such data. In this article, statistics that produce different results were interpreted. In terms of the roles of architects, important data was acquired. According to the printed documents, the architects of 194 (%82,9) out of 234 mosques are unknown. 40 of the mosques (%17,1) were designed by architects. The names of 28 architects who designed these 40 mosques were attained. Of these, 6 architects and 18 mosques belonging to these architects were particularly focused on. In conclusion, this research on the mosques in the central district of Van province showed that the mosque design in Turkey scarcely depends on the professional service of architects.
