Holy Church of the Virgin Mary Pantanassa - Monastiraki

The Holy Church of the Virgin Mary Pantanassa sits in Monastiraki Square, distinguishable by its low-profile, barrel-vaulted stone structure that rests below the modern street level. While historians debate whether the original building dates back to the seventh, ninth, or tenth century, this site served as the katholikon—the main church—of a monastery that once occupied the surrounding square.
