With the raising of the street level in 1941, the mosque remained lower, and the courtyard wall and entrance doors were partially buried.
In the 1940s, the basins and pipes of the fountains on both sides of the courtyard gate disappeared, and today they remain in place as solid marble blocks.
The windows of the narthex have been separated from their original form by being covered with glass and metal.
