  In 1914 this Episcopal congregation on Philadelphia’s Rittenhouse Square installed Mercer tiles in the sanctuary’s aisles and the altar area. The project included more than 10,250 four-inch tiles, which Mercer called his “English Quarry” tiles.
At the altar area are four mosaics depicting the four evangelists, Matthew, Mark, Luke, and John. In 1939 additional pavement tiles were installed for repairs.
