The monastery sits directly on the peak of a 300-meter-tall volcanic plug, which is a remnant of a massive eruption from the Miocene epoch.
The name 'Ypsilos' translates to 'The High One' in Greek, reflecting its prominent position on the island's landscape.
The monastery maintains a small museum that holds a significant collection of 17th-century wood carvings and portable icons.
It served as a refuge and supply point for scholars and fighters during the Greek War of Independence.
The stone architecture of the monastery incorporates volcanic rock extracted directly from the mountain summit.
The Ypsilos Monastery, dedicated to Saint John the Theologian, is the oldest monastery on the island of Lesvos, situated on the summit of an extinct volcanic cone near Antissa. Founded in the 9th century, it played a significant role as a center of religious and educational life during the Ottoman occupation. The monastic complex is built into the volcanic rock, featuring a katholikon decorated with frescoes dating from the 17th century. It houses a collection of ecclesiastical relics, including silver-bound gospels, liturgical vestments, and rare manuscripts. The site is part of the Lesvos UNESCO Global Geopark due to its unique geological position atop a basaltic volcanic plug. The monastery offers panoramic views of the Sigri region and the Aegean Sea. Despite historical periods of abandonment, the site has been preserved and remains an active religious site.

Wear sturdy footwear with good grip, as the terrain around the volcanic summit is uneven and rocky.
Bring a windbreaker, as the high-altitude, exposed location causes the area to be significantly windier than the surrounding plains.
Combine the visit with a trip to the nearby Petrified Forest of Lesvos.
Avoid attempting to visit during high-wind weather alerts, as the exposed cliffside path becomes hazardous.
Visitors must dress modestly, covering shoulders and knees; avoid loud conversations within the monastic courtyard.
