At the location of the chapel of Agio Pnevma (the Holy Spirit) on top of Mount Vrysinas, with an elevation of 858m, archaeologists have discovered what is likely the most significant Minoan Peak Sanctuary in West Crete, the peak sanctuary of Vrysinas. From this vantage point, one can see the northern coast of Rethymnon and the province of Agios Vasilios to the south.
Excavations at this open-air sanctuary have uncovered extremely important findings dating from 1900-1050 BC. The Minoans offered hundreds of zoomorphic and anthropomorphic clay offerings to their goddess. In 2011, a red steatite seal was discovered, engraved with the oldest known Minoan language, the hieroglyphic script. This is the only known example of this script in West Crete.
