St. Joan of Arc Parish, Harrowgate

This Roman Catholic parish was founded in 1919, but the present church building dates to 1946.

The mosaic roundels of the twelve apostles located between the nave's arches were made by Salviati sometime before 1889 and they were listed on the firm's inventory for the 1893 World Columbian Exposition (or the Chicago World's Fair).

The roundels were initially installed in Philadelphia's St. James Episcopal Church, which was built in 1871 after designs by architects Frasier, Furness and Hewitt. However, this church - on the corner of Walnut and 22nd Streets - was sold in 1945 and subsequently demolished.

In May 1947, the Philadelphia Inquirer reported that the mosaics were being re-installed in St. Joan's. As of September 2013, there was the possibility that St. Joan's would be merged with another local parish and the building would be deconsecrated and sold.

St. Stephen's Church, Philadelphia

Built 1822-23, this Episcopal church was designed by architect William Strickland in the emerging Gothic revival style.

The original reredos in 1860.

The church underwent extensive renovations in 1878 under the direction of Frank Furness and it was at this time that it was decorated in the high Victorian style.

Henry Holiday designed the cartoon for the altar reredos that was completed in July 1888 and unveiled in January 1889. Measuring twelve by five feet, it was executed mostly by Salviati's mosaicists, although all of the heads were personally done by Holiday and his wife. It contains over 180,000 tesserae depicting The Last Supper and it is very similar to Holiday's reredos in St. Chad's Church in Kirkby, England.

Incidentally, the church was built on the site where Benjamin Franklin famously flew his kite.
