The roof of Heydar Aliyev Cultural Centre in Baku, designed by Zaha Hadid, was hit by a fire last week, with 1,000m² of the roof damaged by the blaze.
No-one was injured due to the fire, which took place on Friday 20 July and was extinguished the same day.
The interior of the 52,417m² centre – which opened in May this year – remained undamaged according to the Azeri Ministry for Emergency Situations.
The five storey building is named after former KGB chief and ruler of Azerbaijan Heydar Aliyev and contains a conference hall, three auditoriums, a library and a museum.
It is thought the fire occurred due to a failure to comply with fire regulations during welding on the roof.
Azerbaijan’s Prosecutor General is investigating whether fire safety laws were broken and three people were detained by police, reported Trend News Agency.
