St Saviour's Church, St Saviour's Road, W Croydon
(not being brought up in an observant family myself, I get a bit confused by the prefixes Saint and Holy – I've always thought of saints as extra-good people, generally identifiable as such by the gruesome way in which they were put to death. But "Saint" is just a derivative of "Sanctus" or "Sancta", simply meaning holy in Latin, so St Saviour means Holy Saviour. I'm no theologian, but surely that's piling Pelion upon Ossa – if ever anyone was holy, it was Jesus. I look forward to being educated about these niceties.)
