The hotel was located in Dublin's principal thoroughfare, Lower Sackville Street, described by
William Thackeray as an "exceedingly broad and handsome" street.
Dublin Corporation voted to rename the street as
O'Connell Street on 4 May 1924. Writing in 1844, and by way of tourist advice the German, Herr J. Venedy, wrote of the hotel: of Sackville Street with Imperial Hotel after expansion to eleven bays wide with the name inscribed between the floors, on the entrance awning and on the flag Pictorial evidence from 1850 shows a four window wide building at 21–22 Lower Sackville Street opposite the
General Post Office. The hotel name certainly was in use from at least 1843. In 1853, it was rebuilt by William Francis Caldbeck, an amateur architect, into an eight window wide building that also housed Clerys department store in the building's lower floors with the Imperial Hotel on the three upper floors whose street number was then 21–27. The ground floor department store had very tall large
plate glass windows. In the
Alexander Thom's 1863
almanac, James H Coleman is the manager of the hotel. In
Charles Bianconi's biography, written by his daughter Mary Anne, wife of
Morgan John O'Connell, Bianconi is described as frequenting the Imperial Hotel in the 1860s. He reputedly did so because of its convenient location, including its closeness to the departure points of many of his own
coaches, called
bians, and its proximity to the General Post Office opposite. Even when he was wheel-chaired about it was a favorable place where he would meet his friends, and he is said to have done twice as much business in a day as anyone else would complete in two. He used to say that "he could ask them to come when he liked, and he could send them away when he likes." In 1875
William Martin Murphy, having moved his business headquarters from Bantry to Cork and thence to Dublin, bought the hotel and department store in addition to his other business interests. To enlarge the premises to an eleven window wide facade, around 1902 three additional bays were added by Dublin architect George Coppinger Ashlin. Ashlin also added the complex
wrought iron canopy over main entrance featuring the hotel's name interwoven, made by Fagan & Son. The building remained in this format until its destruction in 1916. ==Mail==
