Calcanhar Lighthouse was constructed to help guide vessels through stormy waters. Still an important feature of the landscape today, it's bound to have a few stories to tell about sailing triumphs and tragedies.
You'll have no end of sightseeing choices in Touros. Calcanhar Lighthouse is a great place to start here, but there are plenty of other interesting attractions to check out. Praia do Cajueiro, and Igreja Bom Jesus dos Navegantes are close to the longstanding beacon and will round out your day nicely.
