Proussos Monastery, also known as the Monastery of Panagia Proussiotissa, serves as one of the most significant religious and historical landmarks in Central Greece. Located about 30 kilometers south of Karpenisi, the monastery stands high in the mountains of Evrytania. 

According to tradition, the story of the monastery begins in the 9th century during the time of Byzantine iconoclasm. A monk fleeing from Asia Minor carried with him a sacred icon of the Virgin Mary from the city of Proussa (modern-day Bursa in Turkey). As he crossed Greece, the icon disappeared. Locals later discovered it inside a cave near the current location of the monastery. 

They believed the Virgin Mary had chosen the site herself. As a result, they built a small chapel around the cave. Over time, the chapel grew into the present-day monastery. Today, the icon of Panagia Proussiotissa remains the spiritual center of the monastery. Many people believe the icon performs miracles, especially healing the sick and protecting travelers. Every year, thousands of pilgrims visit the monastery, especially during the feast day on August 23. 

The monastery itself showcases traditional stone architecture. Visitors can see the katholikon (main church), where detailed frescoes from the 16th and 17th centuries cover the walls. Additionally, the original cave that once held the icon still exists as a chapel within the complex. 

To reach the Proussos Monastery, travelers must follow a winding mountain road. Although the road offers stunning views, drivers should remain cautious, especially during winter months or heavy rain. Free parking is available nearby. 

Moreover, the nearby village of Proussos provides options for food, lodging, and supplies. Local tavernas serve traditional Greek meals, while guesthouses offer comfortable accommodations. Hikers also find the area appealing, as several trails connect the monastery to surrounding natural landmarks and mountain viewpoints, such as the “Mavri Spilia”.
