oa On One Architectural Description Given by P. Pallas

The article is devoted to the description of the destroyed Great Mosque in the Crimean city of Kefe, made at the end of the 18th century by academician P.S. Pallas. This document is used to this day to reconstruct the appearance of the building, although its content contradicts the architectural logic. Pallas's description does not match the range of textual and pictorial evidence left by his contemporaries. The whole complex of sources is considered and a conclusion is made about the unreliability of this description as a basis for the reconstruction of the main architectural volume of the mosque.
