On 9 December 2007, a large storm struck the area of Raz de Sein, a stretch of water located between the Isle of Sein and the Pointe du Raz in Finistère in the Brittany region of France. In this mesmerizing video, giant waves are seen crashing against the various lighthouses in this violent area. The footage really gives you an appreciation for the raw power of the ocean.
The Raz de Sein is an essential passage for vessels wishing to pass between the Atlantic and the English Channel because further west at high tide the Isle of Sein and its embankment stretch for more than thirty miles. The area is a dangerous zone for navigation due to the violent sea currents from the tides (up to six knots during the spring tides). The current causes the sea to rise quickly and it is strongly recommended that heavy vessels should only attempt to cross this strait at still water during calmer conditions. [source]
