Dionysios again visited Trebizond in 1377 to collect the rest of the imperial donation, but when he returned, he found that the monastery had been plundered by pirates. The monks were scattered around the surrounding mountains, where they had fled to save themselves. Dionysios did not quit; rather, he gathered them again and continued building the complex and, of course, the walls that would protect them from similar invasions. He also visited Trebizond a third time, where he died in 1390 at the age of 72.
