Leintz Gatzaga (Spanish, Salinas de Léniz) is a town located in the province of Gipuzkoa, in the Autonomous Community of Basque Country, northern Spain.

It is situated in a mountainous area with steep hillsides, wooded and with almost no flat agricultural land.

[citation needed] The history of this village is linked to two factors: the salt mines and the road.

Salt mines have operated in the area since the Iron Ages, leading to the foundation of the village.

[2] Before the village was formed, there were some farmhouses and small towns that were protected by the Castle of Aitzorrotz.

[citation needed] The salt mines were of major economic importance and led to some disputes.

Although the ramparts disappeared, it is still possible to see the five door entrances as well as numerous palatial houses of interest with their shields and coats of arms on the facades.

There are several religious monuments as Dorleta sanctuary, located outside the village next to the salt mine, The Church of San Millan, built in the fourteenth century and reconstructed in the sixteenth.
