The Agios Ioannis Kynigos (St. John the Hunter) Monastery is located on the northern side of Mount Hymettus, above the suburb of Agia Paraskevi.

Built in late 12th or early 13th century, the monastery’s catholicon (main church building) is a cruciform, double-column sanctuary. Among the prominent names mentioned in the monastery’s inscriptions are John the Baptist and Philosophos, a monk believed to come from the Philosophon Monastery in Arcadia.

The catholicon, along with the western pillar, has been well preserved and reveals a basic ‘rubble technique’, which involves overlaid rocks and brick-covered limestone. Marble is generously employed throughout the monastery. Built in the later years, the nave and catholicon are adorned with frescoes, while some Byzantine-era frescoes are partially visible in older sections of the monastery.

Today, the monastery operates as a nunnery.
