Île Noire Lighthouse, Maritime lighthouse in Plouezoc'h, France

The Île Noire Lighthouse is a square tower of light grey masonry rising from a rocky islet in the Morlaix bay. Its lower tier forms a wider rectangular base with a white door reached by a short stair, while the narrower upper tower has small slit windows and a flat projecting cornice. A red dome with a metal spire and cross tops the structure.

The tower was completed in 1845 following a petition from captains in 1841 to improve maritime safety in the region. Engineer Aumaître designed the structure in 1843 and set in motion an important shift in navigation history.

The name Île Noire is tied to the Tintin album of the same title, but Charles Dierick of the Studios Hergé states that Hergé's smugglers' island is not this islet. The square tower does not resemble a defensive work, and the islet can be reached at low tide. Navigators still use the light, together with the Lande lighthouse, to line up the entry to Morlaix through the Tréguier channel.

The lighthouse stands on a rocky islet in the Morlaix bay, almost entirely submerged at high tide, so it can only be reached at low water. It is no longer guarded or inhabited. Boats to the area leave from Carantec or Plougasnou, and the rocks are slippery underfoot.

The islet is almost entirely submerged at high tide, so the tower can only be reached on foot at low water. Charles Dierick of Studios Hergé stated that this square tower is not the island of the counterfeiters in Tintin's L'Île Noire, since a square lighthouse does not resemble a defensive work.
