Phare des Grands Cardinaux
Phare des Grands Cardinaux, Maritime lighthouse on Groguéguez rock near Hoëdic island, France
The Grands Cardinaux lighthouse stands 27 meters tall on a rocky outcrop, featuring a white light that flashes four times every 15 seconds.
Construction of the navigation structure was completed in 1875, and the lighthouse underwent automation processes in 1973 to modernize its operations.
The lighthouse earned recognition as a historical monument in June 2020, marking its importance in French maritime heritage and coastal navigation.
The lighthouse beam reaches 12.5 nautical miles, providing essential guidance to vessels approaching the Bay of Quiberon from its strategic position.
The structure operates through remote control from the Goulphar lighthouse and appears on marine charts under the name Grogueguez.
