Over the course of battles for the airport, the airport complex suffered extensive damage from constant bombardments and change of hand between pro-government and proxy forces. The main terminal buildings, with their sturdy concrete construction, served as garrisons and shelters for soldiers defending the airport grounds, and as a result the buildings would be subjected to attacks and suffer extensive structural failures, most notably with the collapse of the massive roof over the new terminal building's mezzanine. Similarly, the control tower was contested by opposing forces due to its strategic lookout point, but eventually collapsed in January 2015 during the final leg of the Second Battle of Donetsk Airport.
