Penly Nuclear Power Station stands near to the shore, 5.4 miles NE of Dieppe. It is fronted by a prohibited area, which extends up to 0.8 mile seaward and is marked by lighted buoys. A narrow winding channel leads between short breakwaters to the power station.
A prominent radio mast stands about 0.8 mile SE of the power station.
Caution.—Numerous wrecks lie along this stretch of the coast and may best be seen on the chart.
A former mined area, which is open to surface navigation, is still considered to be dangerous by the French authorities with regard to anchoring, trawling, or carrying out any sea bed activities.
