Before 1866, the powder magazine was in the southern part of the interior.
Slightly before the Turkish attack, and in fear that it could easily be broken into and the monastery blown up, the munitions were moved to the cellar, which was situated approximately 75 centimetres below where it had been originally placed, which was more secure.
The powder magazine is an oblong vaulted building.
It is 21 metres long and 5.4 metres wide and was destroyed entirely during an explosion in 1866, with the exception of a small part of the vault in the western part of the room.

In 1930, the archbishop Timotheos Veneris placed a commemorative inscription which was fit in the eastern wall in remembrance of the events of 1866.
The inscription reads:
The flame which lights the depths of this crypt
was a godly flame in which

the Cretans perished for freedom
