Les Casquets, Rock formation near Alderney, Guernsey
Les Casquets consists of multiple rocky outcrops emerging from an underwater sandstone ridge in the English Channel, positioned 8 miles northwest of Alderney.
The construction of three separate lighthouses on Les Casquets in 1724 marked a significant advancement in maritime navigation for vessels traversing the English Channel.
The dangerous nature of Les Casquets inspired Victor Hugo's writings in 'The Laughing Man', where he detailed the different destructive effects of shipwrecks on these rocks.
Access to Les Casquets requires careful planning due to strong currents reaching speeds of 7 knots, making boat navigation particularly challenging during adverse weather conditions.
The waters surrounding Les Casquets serve as a nesting ground for numerous seabird species, including puffins and guillemots, which return annually during breeding season.
