[7] The Neoclassical architecture of the hall is a constant reminder of early British influence in the administration of Ibadan as part of the Oyo Province.

Over the years, the hall had played host to major political and social events in the city, shaping the socio-political direction of Nigeria in general.

The Sixth Annual Convention of the National Council of Nigeria and the Cameroons was held there on 5 May 1955 and that was where Nnamdi Azikiwe delivered his presidential address.

In Campaigning for the 1983 elections, Chief Awolowo also held a campaign rally there in 1983 where he made the famous quote - "Kaka ki Kiniun se akapo Ekun, kaluku a ya se ode ti e l’ototo ni," meaning "the Lion would rather hunt separately rather than be the bag bearer for the Tiger."

Mapo Hill, the site of the hall, is one of the oldest part of Ibadan city, a high density area occupied mainly by the indigenes of the town.
