 The Unicorn building largely dates from the 17th century with evidence of earlier origins. It is situated on what was in the 18th century the main road from London to Berkhamsted. The first mention of the building as licensed premises is in 1756 when it was run by Francis Knowles who was also a sawyer. In 1768 it was owned by Nathanial Hitchcock who was a wheelwright from Hunton Bridge. In 1786 it was sold to John Smith who  was a Watford brewer and subsequently it was brought by Peter Clutterbuck, brewer of Stanmore.  (Hertfordshire Inns and Public Houses)
