"Platte Fougere Lighthouse"

The Platte Fougere Lighthouse marks the northern end of the Little Russel, being the main approach to both St Peter Port and St Sampsons harbours (from that direction). It is one of the most significant lights within Guernsey Ports' responsibility.

It is a red and white sectored light; the red sector covering the Brayes rocks. The current structure was put into service in 1910. The light is LED standard.

Please note, the Platte Fougere foghorn is currently not operational.

"Fourquies" North Cardinal Buoy

Cardinal marks indicate the direction of safety as a cardinal (compass) direction (North, East, South or West) relative to the mark.

The "Fourquies" North cardinal is positioned to the North of the Fourquies reef and indicates to mariners that the danger lies to the South of the buoy. Due to the relatively deep water where the buoy is positioned, mariners should exercise caution in the area as the buoy will move in the tidal stream, particularly at low water. Its position can be seen on the illustration.
