Standing in the central space of the congregation hall of the mosque, and looking towards the entrance at its north side. Above the door, a platform for the singers has been arranged; on special occasions – the last evening of Ramadan, Kandil (= birthday of the prophet Muhammad), and other – the solemn prayer can be accompanied by a male chorus reciting sacred texts.
The platform was not part of the original 14th century draft; it has been added during some later restoration.
The marble ‘şadırvan’ (fountain for ritual ablutions) also dates from the 1904 restoration; some sources suggest it too was not part of the original 14th century draft.
The murals (also dating from the 1904 restoration) are an example of late-Ottoman style, mixing 16th century classic design with 19th century Turkish ‘Baroque’, influenced by European Neo-Classicism.
