The southernmost estuary in Galicia is the Ria de Vigo. It’s also the deepest, with a great biological wealth thanks to the deep, cold currents of water from the North laden with nutrients. It stretches 35 kilometres from Cape Silleiro, measuring 600 metres at its narrowest, in Rande. So narrow that it gives the impression it’s going to open up later into a kind of lagoon or second bay in the cove of San Simón.
Precisely this narrow place, where the famous cable-stayed bridge was built, was the site of the battle of Rande. A disaster for the Spanish Crown, who saw how the riches brought from America were shipwrecked by the attack of the Anglo-Dutch squadrons.
This also happened to be the spot chosen by Jules Verne for one of the adventures of the Nautilus in 20,000 Leagues Under the Sea.
