Matthew snapped a photo of this mural that shows the inner courtyard of the Blue Mosque. In the center is an old fountain once used for ablutions (ritual washing) before prayer. New washing stations sit along the wall at the entry to this courtyard to accommodate more people. When the mosque itself fills up on special holy days, the overflow population prays here in the inner courtyard. I guess Muslims have their equivalent of “Chreasters,” too (Christians who attend services only on holidays like Christmas and Easter).
