Take a close look at the tower's masonry. It stands 26 meters tall on land, rising to a focal height of 34 meters above the high-tide sea level. It was constructed using high-quality granite blocks hauled from the historical Aber-Ildut quarry just to the north. In the community of lighthouse keepers, Petit Minou was known as a paradise lighthouse because it was connected to the coast and actually featured several rooms where keepers could stay with a modicum of comfort. However, the era of the resident keeper ended in 1989 when the light was fully automated. Today, its beam still reaches out 19 nautical miles, which is nearly 35 kilometers, and is controlled remotely from a maritime center in Brest. Despite this high-tech brain, the lighthouse still rests on its nineteenth-century stone foundations, enduring every winter storm the Atlantic can throw at it.
