The Monastery of Chountalos is today in ruins and lies near the abandoned village of the same name. According to tradition, it was a Byzantine monastery that was destroyed by Ibrahim during the Greek Revolution. What survives today is the church and a small section of the monastery’s outer wall. The church was once entirely covered with wall paintings, of which only a few Byzantine‑period frescoes remain.

The fortified enclosure has collapsed in many places, and within it the remains of monastic buildings can still be discerned. The katholikon is dedicated to Saint Nicholas of Vounaina. It is a single‑aisled structure that originally had a vaulted roof, now replaced by a pitched, tiled covering. The sanctuary apse is semicircular, the templon is built of masonry, and the entrance to the church is located off‑center on the northern side. Inside, fragments of 17th‑century frescoes are preserved.

Both inside the church and in its surrounding area, several Byzantine sculptures have been identified, including two Early Christian marble reliefs, an impost block and a chancel screen slab with an inscription, as well as a marble plaque bearing a seven‑line inscription in capital letters, dated to the late 18th or early 19th century.
