Reg Cundick and Danny Howell in the book The Inns And Taverns Of Warminster, published in November 1987, stated:
The Royal Oak
This was situated on the south side of Fore Street, much further east of the present-day Globe Inn.
It is recorded at Plot No.1487 in the 1838 Survey Of Warminster and referred to as a licensed beerhouse; the licensee being Thomas Hill. According to local directories this inn was still operating in 1852.
The diary of Edward Price, which recalls experiences in both the old and new poorhouse at Warminster during the early part of the 19th century, mentions an old inmate of the Workhouse at the Common with the name of John Poore. He was 70 to 80 years old and looked after the garden and the pigs at the Poorhouse. Price describes how Poore visited the Royal Oak every night, drank a glass of ale and smoked his pipe before returning and retiring to bed at the Poorhouse.
