The oldest church in Letchworth, St. Mary’s has traces of its Saxon origins but is mostly of early Norman construction. It’s a tiny and delightful building on Letchworth Lane with some interesting 19th and 20th gravestones, including one of a Belgian soldier of the First World War, paid for by work mates from the factory where he was employed before the war. Unfortunately, like so many, the church is generally closed. There is some interesting ancient graffiti in the porch but I have been unable to locate any interpretation of it.
