Landsort lighthouse tower was built in 1689, with an upper conical iron section added in 1870. Open fires have been lit here since a long time ago. The first 'real' lighthouse was lit in 1651 and, until the now-standing tower was built, a couple of different buildings were used as the lighthouse. The 1689 tower was constructed to carry an open fire which ran on coal. In 1840, a colza oil lamp was installed. The flame ran on paraffin from 1887, and in 1938 it was electrified. Today the Swedish Maritime Administration owns and runs the lighthouse.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
