The Stables for the horse drawn Mono Rail
The Photo above was also taken by Fred McCave in the late 1970's and is reported to be the Stables for the Mono Rail horses. The pole in the background is probably Somnes Avenue so this would be on the north side of Central Wall road near Temple Bar. Needless to say it has long been demolished! Below is an advertisment from the A.A.Daly book for the Mono-Rail Tramway.
