The Holy Monastery of Roussanou has received the name of the first probable hermit who settled on the rock. The main cathedral was founded at the end of the 16th century and was decorated thirty years later.
Compared to other rocks where monasteries were built, the one of Roussanou has a lower elevation, which makes it more accessible. The monastery was initially founded by monks and it suffered severe damage during World War II. It became a convent in 1988.
The beautiful wall-paintings of the Catholic were executed in 1560, when the priest-monk Arsenios was the abbot of the monastery. The unknown hagiographer seems to have been a very skillful artist and successfully follows the Cretan School style.
