Origin and history

The English tower, originally called the Pénerf tower, is located on the peninsula of Pénerf, Damgan (Morbihan). Built probably in the early 16th century, it was attested as early as 1692. This 15-metre-high cylindrical monument served as both a fire tower and a watchtower, integrated into a military ensemble including two batteries until the early 19th century. Its original architecture makes it the oldest fire tower preserved on the French Atlantic coast.

The structure rests on a truncated base of 8.20 metres in diameter, built of stone and restored in 1978. The walls, thick one metre, are made of coated bellows, with granite murderers. A parapet supported by mâchicoulis crowns the building. Owned by Damgan, the tower was listed as a historical monument on 22 October 1997 after restorations in 1886.

Its present name, the English tower, appears only after 1902, replacing the previous names of Tour Blanche and then Tour de Pénerf. Located 100 metres from the shore, it is now a bitter (sea marker) and one of the last testimonies of Breton coastal defensive systems. Its materials, such as coastal stone and granite, reflect local construction techniques.

The archives mention its role in regional defence, with references in 19th century documents (e.g.: Pilot of the coasts between Penmarch and the Loire, 1869). The tower illustrates the evolution of coastal fortifications from military use to a protected heritage, a symbol of Breton maritime history.
