The Monastery of Panagia Eleousa dates back to the 15th Century. It is located in a hidden valley near Glifa. The monastery is the main reason anybody would want to come to Glifa, and in the past, it has attracted mostly German tourists.
Inside the walls of the monastery are a courtyard, a beautiful old church, watchtower, and dormitory. Parts of the walls are over 1000 years old. The monastery survived the Turkish occupation and was never really threatened throughout its history.
No admission is charged, but it is recommended to leave a donation of whatever you feel is enough. There aren't many tourists that stop by, so the abbess is very hospitable.
There is a dress code. No shorts or bare shoulders. Women must wear a skirt that is about ankle length. The abbess may request women cover their heads. Men must wear long pants.
Follow the dirt and gravel roads through the fields surrounding the village of Glifa. You will get some great views of the land, Zakynthos across the Ionian Sea, and the village itself.
Inside the cave you will find some icons, a few religious artifacts, and where the spring of holy water once flowed rapidly.
