Nun spring, Natural spring in Northern District, Israel

Nun spring (Ein Nun) rises in the fields of Moshav Migdal in the Ginosar Valley. Its water collects in a round upper pool about 60 cm deep, with almost no stones, where water plants and filamentous algae grow. From there it flows into a larger, shallow rectangular lower pool with a stone floor, fed also by three small springs; tall eucalyptus and Washingtonia palms stand beside it.

Around the spring, archaeologists found a Roman-era irrigation system with a reservoir pool and an aqueduct that carried water to the nearby town of Migdal. The spring's name preserves the Aramaic name Migdal Nunaya, 'Tower of the Fish,' one of the old names of Migdal. In 2017 the spring nearly dried up, causing severe ecological damage; restoration work began in 2018 and was completed in July 2019.

The name Nun comes from Aramaic for "fish", preserving the name Migdal Nunaya (Fish Tower), one of the old names of nearby Migdal. Volunteers among Migdal residents maintain the spring and keep it clean, which allows free entry to the site.

The spring is accessible through marked walking paths from nearby towns. The routes are easy to walk and provide spots to rest while taking in the natural surroundings.

The water flow changes with the seasons, creating different habitats for plants and wildlife throughout the year. This natural rhythm makes the place look different depending on when you visit.
