It was built in 1966 as part of the now-demolished Divis Flats complex, which comprised twelve 8-story blocks of terraces and flats, named after the nearby Divis Mountain. The tower, a vertical complex of 850 flats, housing 2,400 residents, was designed by architect Frank Robertson for the Northern Ireland Housing Trust. The site on which the Tower stands was previously the site of the Sir Charles Lanyon-designed Falls Road Methodist Church, which opened in 1854 and closed in 1966. The site was sold to Belfast Corporation for approximately £11,000. A television documentary has been made about the tower.
In response to Provisional IRA and INLA activity in the area, the British Army constructed an observation post on the roof in the 1970s and occupied the top two floors of the building. At the height of the Troubles, the Army was only able to access the post by helicopter.
Following the IRA's statement that it was ending its armed campaign, the Army decided to dismantle the observation post. Dubbed a 'spy' post by Sinn Féin, removal of the observation post commenced on 2 August 2005. In 2009, the top two floors of the tower were reinstated as residential properties. As part of a £1.1 million refurbishment programme by the Northern Ireland Housing Executive eight extra flats were provided.
Both Divis Tower and the former Divis Flats have featured in multiple works of popular culture. For example:
In films
In the film '71, new recruits to the British Army, who are deployed to keep peace in Belfast, are told to never enter Divis Flats. However, when a father and daughter find the protagonist lying unconscious in the street, injured by bomb shrapnel, they carry him to their home in Divis Flats and tend to his wounds. Only then do they realise he is a soldier, which presents problems for all three of them.
Divis Tower was featured in the popular BBC Northern Ireland sitcom Give My Head Peace. The fictional characters of Da, Cal, Ma, and for a while Dympna and Emer, all nationalists/republicans, lived in "Flat 47A, Divis Tower". It was first seen in the pilot episode entitled "Two Ceasefires and a Wedding", and a full series renamed "Give My Head Peace" commenced broadcasting in 1998. "Da" was a Sinn Féin assembly man and a staunch republican, who based his family in Divis Tower since the 1970s. The flat was constantly raided by the RUC. It was in the flat that the Protestant character "Billy", a RUC/PSNI policeman, met Da's daughter Emer, fell in love, and married her.
