A year after a fire damaged it irrepairably, the Bank of Lisbon building in Johannesburg was demolished in a controlled explosion Sunday, and a video of it is going viral. The 22-storey building was deemed unfit for occupation after a structural assessment following the fire last September. The fire claimed the lives of three Johannesburg firefighters. Johannesburg's Emergency Management Services tweeted a clip of the demolition and hoped the demolition will bring closure to the friends and families of the fallen firefighters.

Tasneem Motara, Gauteng Member of the Executive Council for Infrastructure and Property Development told Euro News that it was one of the most difficult demolitions they have worked on. Around 2000 people were reportedly evacuated from buildings near the bank before the demolition.
