The photos are of Ely Chapel, St Etheldreda’s Church, a 13th century church once the London chapel of the Bishops of Ely, Cambridgeshire. It is the only surviving London building from the reign of Edward I (1239-1307).  Although a Roman Catholic church again since 1874, in 1836-7, it was an Anglican Church, in the care of Alexander d’Arblay. After its purchase in 1874, the church and crypt were restored by noted architect George Gilbert Scott.
