Mercenaries of the Catalan Grand Company raided the Holy Mountain for two years (1307–9), sacking many monasteries, plundering the treasures of Christendom, and terrorising the monks. Of the 300 monasteries on Athos at the beginning of the 14th century, only 35 were left by the end. But the monastery recovered quickly with the help of grants and support from the Palaeologue Emperors and the princes of the Danubian Principalities. The buildings were reconstructed in the late 13th century with the financial aid of Byzantine Emperor Andronicus II Palaeologus. The monastery was also given numerous "metochia" (properties) in parts of Romania, Bulgaria, Russia, and modern-day Turkey, but retains today only those in Greece.
