Lagos is a municipality at the mouth of Bensafrim River and along the Atlantic Ocean, in the Barlavento region of the Algarve, in southern Portugal. It is one of the most visited cities in the Algarve and Portugal, due to its variety of tourist-friendly beaches, rock formations (Ponta da Piedade), bars, restaurants and hotels, renowned for its vibrant summer nightlife and parties. Yet, Lagos is also a historic centre of the Portuguese Age of Discovery, frequent home of Henry the Navigator, historical shipyard and, at one time, centre of the European slave trade.
