Reg Cundick and Danny Howell in the book The Inns And Taverns Of Warminster, published in November 1987, stated:
The Three Mariners, Warminster
The Three Mariners occupied a site on the north side of East Street, immediately opposite the present entrance to Carson’s Yard. The inn was up for sale in 1706 and was mentioned again in 1715 (WRO 1399/10 and 1399/11). There does not appear to be any other record of it or any details about when it closed.
Following life as an inn, the building was converted into a private house. From about 1824 onwards it was the home of various members of the two families, namely the Carsons and the Toones, who ran the nearby ironworks known as the Wiltshire Foundry. The last of these, William Carson Toone, emigated to Canada in 1903. The house, which was known as Inglebury at that time, was put up for sale by auction, at the King’s Arms Hotel, Warminster, on 18th September 1902. The auctioneer, Claude Barber, referred to the fact (on the authority of Toone’s solicitor, Mr Wakeman) that the property was once a licensed house known as The Three Mariners.
Henry Faulkner opened his “Fancy Bazaar”, selling toys and stationery, on the ground floor of the property in June 1904. After 1915, Ernest Stiles had the shop, selling drapery and furniture. By 1923 it had become a retail outlet for George Bush & Co., who were house furnishers. The building, which was three storeys high, was purchased and demolished after 1968 when plans were proposed for developing the site. This area, behind the General Post Office, is still vacant and awaiting redevelopment today.
