From The West Wiltshire District Guide 1978:
The village of Heytesbury is situated astride the A36 Bath-Southampton trunk road some three miles east of Warminster. Heytesbury has an agricultural history as well as an archaeological and parliamentary one, and much of it can be traced as far back as medieval times.
The village of Heytesbury is very ancient and is mentioned in the Domesday Book as Hestrebe.
The Collegiate Church of St. Peter and St. Paul, Heytesbury, was built in the 12th century, whilst the Angel Inn standing opposite the Hungerford Almshouse, probably goes back to 1400 A.D., and was an old coaching inn.
Heytesbury has few other buildings of historical or architectural interest, probably owing to the destruction of most of the town in its own Great Fire of 1765.
In the middle of Heytesbury High Street there stands one of the curious little “blind houses” an octagonal building with a stone tiled roof containing a dome, in which, many years ago, offenders were locked up by the village constable.
The Hospital of St. John is today the memorial of the famous Hungerford family, for apart from this almshouse, and the sickle badge on the screen of what remains of the old Hungerford Chantry of St. Michael in Heytesbury Church, there is nothing left to show that the Hungerfords ever lived here.
