A blue plaque for a national hero in St Albans

A blue plaque for a national hero in St Albans is shown and named in a reusable Geograph picture. The saved point is the picture's recorded map point.

The plaque commemorates John Oldcastle, a Lollard leader who fought against the Catholic Church's authority in England, becoming a symbol of resistance and reform; his actions influenced later Protestant movements despite his execution for heresy.
