This is one of very few pictures which have survived showing the interior of the church before a disastrous fire in 1945 destroyed much of the original. There were stained glass windows above the altar, mosaics featuring gold leaf and lapis lazuli decoration and a superb mosaic floor in the chancel. All apart from a tiny fraction of mosaic on the wall of the sanctuary were lost. In fact trouble began earlier; by 1895 the chancel was unsafe due to ground movement and the original stone chancel and sanctuary arches were replaced by wooden ones. Sadly the 1945 fire also destroyed the fine lofty timber roof, organ and chancel screen.
St. Saviour’s has more stained glass than any other church in Walthamstow; most of it takes the form of memorials to former members of the congregation, clergy or their families. The most beautiful were undoubtedly the windows at the east end above the altar which were destroyed in the fire in 1945.
