Historical Background and Archaeological Significance

Origins and Early Use

The Klepsydra Spring has been a vital natural water source since the Neolithic period (ca. 3500–3000 BCE). Archaeological evidence reveals that ancient Athenians dug wells up to 5 meters deep to access the underground vein, making this spring one of the city’s oldest (Hydria Project; Klepsydra Suites). During the Mycenaean period, the spring was incorporated into Acropolis fortifications, a response to the constant threat of invasions.

Classical and Later Developments

By the fifth century BCE, the spring was formalized into a stone-built fountain house, with a paved court and a deep basin. The name “Klepsydra”—Greek for “water thief” or “water clock”—refers both to its intermittent flow and to the ancient timekeeping devices that used water, reflecting the spring’s cultural resonance (ASCSA Hesperia; Wikipedia).

Over the centuries, the site underwent continual enhancements. It was reconstructed after landslides and earthquakes, with Roman and Byzantine modifications including new well-houses and chapels. The spring was rediscovered and protected during the Greek War of Independence in 1822, and major excavations by the American School of Classical Studies in the 20th century revealed the full extent of its structures (ASCSA Hesperia).

Religious and Cultural Importance

The Klepsydra was more than a practical water source; it was also a center of religious significance. The spring was associated with the nymph Empedo and was believed to be protected by divine forces. Worship of the nymphs, especially the Naiades, and proximity to sacred caves and the sanctuary of Apollo, cemented the area’s spiritual role in Athenian life (ASCSA Hesperia; Klepsydra Suites).

The site’s sacred status persisted through history, with Christian chapels erected during the Byzantine period and continued reverence for the spring’s healing properties (Hydria Project).

Engineering and Structural Evolution

The Klepsydra site is a showcase of ancient engineering. Early Athenians built polygonal limestone walls and wooden bracing to support the well-house against landslides and seismic activity. A vaulted corridor with 70 steps was added during the Roman period to ensure year-round access. Water from the spring was distributed via terracotta pipes and cisterns, servicing public fountains and baths (Hydria Project; ASCSA Hesperia).

Continuous adaptation and repair are evident throughout the site’s history, highlighting both its practical and symbolic value to Athens. Even during the Nazi occupation, the ancient passage near the spring was used by Greek resistance fighters in an act of defiance (Hydria Project).
