The entire complex is well worth seeing. It features numerous old mills lined up next to each other. The valley was once covered with mills from top to bottom. Even today, it's still an exciting complex, even though most of it has fallen into disrepair, the structure is still clearly recognizable.

The Fornelos salt pans, dating back to the Iron Age, are located above the high-tide mark, preventing them from being flooded when the tide reached its maximum level. This suggests they operated through an indirect flooding system, whereby salt miners would flood the pans with water brought from the sea.

Nestled in a small cove, Fornelos Beach is worth a visit in itself, but here we also find an interesting series of petroglyphs carved into the reddish rocks. These engravings, carved into two boulders, date back to the Bronze Age, specifically between the 3rd and 8th centuries BC, and protrude several meters above the sand. We can make out serpentine motifs, schematic zoomorphic figures, particularly deer, dimples, horseshoes, and grooves carved into the rock, presumably depicting a hunting scene. https://www.altominho.pt/pt/visitar/o-que-ver/gravuras-rupestres-da-praia-de-fornelos/

At the end of Praia da Liberdade, near the river, stands the monument dedicated to April 25, 1974 (Estátua do 25 de abril or Estátua da Liberdade), a tribute to the people of Viana who fought for freedom. This sculpture by José Rodrigues was inaugurated on April 25, 1999. Beautiful for photos; the fountains create a small water feature show.
