Monto was the nickname for the one-time red light district in Dublin, the capital of Ireland. Monto was roughly the area bounded by Talbot Street, Amiens Street, Gardiner Street and Seán McDermott Street (formerly Gloucester Street). The name is derived from Montgomery Street (now called Foley Street), which runs parallel to the lower end of Talbot Street towards what is now Connolly Station. It was immortalised as "Nighttown" in the "Circe" chapter of James Joyce's famous work, Ulysses, where the central protagonists Leopold Bloom and Stephen Dedalus together visit a brothel.
In its heyday from the 1860s - 1920s, there were anything up to 1,600 prostitutes working there at any one time, with all classes of customers catered for. It was reputed to be the biggest red light district in Europe at the time. Its financial viability was aided by the number of British Army barracks and hence soldiers in the city, notably the Royal Barracks (later Collins Barracks and now one of the locations of Ireland's National Museum).
Monto was also a hive of IRA activity, particularly around the time of the war of independence, with several safe houses for the flying columns which included Phil Shanahan's public house.
The then Prince of Wales, Prince Albert Edward (later King Edward VII), according to popular legend, lost his virginity there. In the 1880s the Prince, accompanied by his wife Alexandra and their son Albert Victor, Duke of Clarence strolled unrecognised through the area, having slipped away from their bodyguards and walked through Dublin.
