The oldest structure in the county, the Saxon tower of this Franciscan church was built around 1025. The round holes above the belfry windows were designed to offer owls nesting privileges; they were valued as mouse killers. The church also has a Bible that belonged to Thomas Hobson, owner of a nearby livery stable, who told customers they could hire any horse they liked as long as it was the one nearest the door - hence the term 'Hobson's choice', meaning no choice at all.
