The monastery played an active role in the Cretan resistance of Ottoman rule during the Cretan revolt of 1866. 943 Greeks, mostly women and children, sought refuge in the monastery. After three days of battle and under orders from the hegumen (abbot) of the monastery, the Cretans blew up barrels of gunpowder, choosing to sacrifice themselves rather than surrender.
The monastery became a national sanctuary in honor of the Cretan resistance. 8 November is a day of commemorative parties in Arkadi and Rethymno. The explosion did not end the Cretan insurrection, but it attracted the attention of the rest of the world.
