The elaborate Caverhill Hall on Sydney Street, Saint John, was originally home to the former mayor of Saint John, Simeon Jones. The site gets its name from Jones' mother's maiden name. Fitting of its owner's prestigious status, its impressive construction stands out from its surroundings. Inspired by a mansion Jones had seen in Toronto, Caverhill Hall is a Baronial Gothic castle-like mansion, built from limestone and ornamented with balustrades, pillared balconies, and towers. The interior contains several luxury features, including a music room, libraries, an octagonal hall, and wall-embedded Victorian paintings.

Simeon Jones' political career started when he was elected to the city council in 1879 and continued after he was elected mayor in 1881. He left office in 1884, around the time this house was constructed. Outside of politics, he was a brewer, crafting high-quality ales alongside his 12 employees. In the present, the Picaroons Brewing Company sells an ale named after him.

In later years, ownership of Caverhill Hall was handed to Simeon's son, Robert Keltie Jones. In 1901, Robert lent the mansion as a temporary residence to the Prince of Wales (who later became King George V), as well as to the Duke and Duchess of Cornwall and York. In about 1914, the Jones family left the house, and it was soon adopted by the Canadian military as a WWI headquarters. In 1923, the building was purchased by the municipality and converted to the St. John Health Centre. When the Second World War broke out, it was given to the military again, this time serving as a recreation center for the Royal Canadian Air Force. It remained the Royal Canadian Air Force Social Club for over twenty years afterwards.
