Punta na de la Orchilla - a lighthouse situated near the municipality. The lighthouse was first constructed to represent the old meridian. It used to mark the meridian line or the 0 degree-line at the lighthouse which was put by the French in 1634. Many 16th and 17th century maps had the meridian facing at Punta de la Orchilla until 1885 when the meridian since that time moved east to Greenwich during the conference in Washington D.C.. Before the meridian change, El Hierro was known as Isla del Meridiano (Meridian Island).
