The three-storey building, designed by Sir Charles Lanyon, stood in a commanding position across the junction from the Bank Buildings.
It was built in the Regency style, stuccoed, with a cast-iron balcony attached to a bow-fronted central bay.
The Club-house was built about 1863, though swept away for Calvert House (1983-4), a four-storey glass structure, in 1981.
I recall the Ulster Club, which was derelict and ruinous, at the height of "the Troubles", before it was demolished.
Presumably the 5th Earl of Enniskillen was staying in the club when he received the calamitous news that his ancestral seat in County Fermanagh, Florence Court, was on fire.
Lady Enniskillen telephoned him at the club and he was said to have retorted, "what the hell do you expect me to do?", or words to that effect.
The Club sold its premises at Castle Place in the late 1960s and leased one floor of River House, in High Street.
It merged with the equally celebrated Ulster Reform Club in 1982.
