Salt Mines d’Es Trenc and its ethnographic heritage

The rich environment of Es Trenc Salobrar National Park is complemented with a resource that contains impressive historical heritage for Campos.  The cultural footprint of the Salt Mines d´Es Trenc and its ethnographic heritage are validated by the fact that both Romans and Phoenicians obtained the valuable condiment from this area since ancient times. Over time, the salt produced in Es Trenc acquired importance until reaching the point of providing an impressive trade activity in the middle of the twentieth century.

Nowadays salt mines such as d’Es Trenc have lost their purpose and traditional importance however the use of the Flor de Sal d’es Trenc proves that its future lies in innovation. These delicate crystals which are formed at the bottom of the salt ponds are considered to be a delicacy.  Enriched with natural ingredients, ingenious combinations with Mediterranean herbs, olives, hibisco and all types of spices have been created.  With the same importance as in the past, this salt is included in Balearic gastronomy as an indispensable item. The extraction of Flor de Sal d’Es Trenc is a completely natural phenomenal. It requires specific weather conditions: a lot of sun, soft breeze and low humidity which usually occur at the end of August or beginning of September.
