Poulains Lighthouse, or Phare des Poulains, stands on the northernmost tip of Belle-Île-en-Mer in Brittany, France. The tower was constructed in 1868 and marks the entrance to the Quiberon Bay. The site includes the lighthouse keeper's house, which now functions as a space for exhibitions. The surrounding Point of Poulains is a protected natural site characterized by rocky cliffs and Atlantic exposure. Sarah Bernhardt, the famous actress, purchased the nearby fort and resided on this peninsula for many years. The lighthouse was fully automated in 1987 and remains an active aid to navigation. Its light signal flashes white every five seconds. The site is managed by the Conservatoire du littoral to preserve its unique maritime landscape.
