Marierrota is a tide mill located at the end of the Senda del Lea (Lea Trail), at the mouth of the river between the beaches of Isuntza and Karraspio, which exploits the tide cycle to generate a waterfall that drives the mill.
It was built in 1555 in order to supplement the mills on rivers in times of drought and still has the rough stone dyke that stored the water which, when the tide began to ebb, set the mill machinery in motion.
The mill building, demolished in the eighties, was rebuilt and today houses a Biodiversity Visitor Centre to discover the wetland and the activities that went on at Marierrota over more than five hundred years.
