The Athenaeum in Princess Street Manchester, England, now part of Manchester Art Gallery, was originally a club built for the Manchester Athenaeum, a society for the "advancement and diffusion of knowledge", in 1837. The society, founded in 1835, met in the adjacent Royal Manchester Institution until funds had been raised for the building. The society survived financial difficulties to become the centre for Manchester's literary life. It ceased operations in 1938.
Sir Charles Barry designed the Athenaeum building in the Italian palazzo style, the first such building in the city. Manchester Corporation acquired the building in 1938.
In 2002, Manchester Art Gallery was extended by Hopkins Architects following an architectural design competition managed by RIBA Competitions to take in the Athenaeum. It is linked to the art gallery by a glass atrium. The Athenaeum is a grade II* listed building.
The Manchester Athenaeum for the Advancement and Diffusion of Knowledge was founded in 1835, with James Heywood as its first president. It met initially at the Royal Manchester Institution until funds had been raised for its own building, which was completed in 1837. Their new premises had a newsroom on the ground floor, and a library, lecture hall and coffee room. A billiards room and gymnasium were added later.
Richard Cobden was instrumental in promoting education in the city and spoke at the opening. He, along with a significant number of other members of the Anti-Corn Law League's Council, was an important figure in both instigating and developing the society during its early years. He described it as a "manufactory for working up the raw intelligence of the town".
