Issanka, park in Balaruc-le-Vieux, France

Issanka is a park and lieu-dit at the edge of Poussan, near Balaruc-le-Vieux and Gigean in the Hérault. Its spring rises on the right bank of the Vène, fed by resurgences from the causse d'Aumelas, and has supplied Sète with water since 31 August 1862.

In 1862, the natural spring was captured and diverted to supply water to Sète, fundamentally changing the site's original purpose. This action redirected the course of the place's development.

The site's name appears as Liscenca in 1759 and Lissanka in 1865. A local saying holds that once you have tasted Issanka's water, you can never do without it. A song, the Festa dé l'Issanka, is tied to the spring.

The spring lies on the right bank of the Vène, at the edge of Poussan near Balaruc-le-Vieux and Gigean. The site is a park and lieu-dit around the source; access is from the local roads. The water is captured for Sète's supply, so the immediate catchment area is not open for wandering.

The spring's water was already captured in the 1st century and carried to the Roman thermal baths of Balaruc by the aqueduct of Balaruc. A local saying holds that once you have tasted the water of Issanka, you can never do without it.
