Over 200,000 bees living in hives on the roof survived the devastating fire, BBC reported.

Nicolas Géant, the cathedral's beekeeper, has confirmed that the bees are alive and buzzing. Géant has looked after the cathedral's three beehives since 2013, when they were installed. That was part of an initiative to boost bee numbers across Paris.

The fire broke out at around 6:30 pm Monday, and the roof, the clock and spire was damaged. According to preliminary reports, the fire started during the restoration works. The French authorities said large fire has been extinguished. Paris municipality will allocate 50 million euros for restoration of Notre Dame cathedral which was heavily damaged because of fire.
