Tower

The Tourelle de la Plate, also known as Petite Vieille (, "Little Old Woman") is a lighthouse in the dangerous strait Raz de Sein, off the northwest coast of France, belonging to the departement of Finistère in the region of Brittany. Its companion light, La Vieille, is 260 metres to the north-east. At a meeting on 5 June 1886, the lighthouse commission decided to construct a new tower near the La Vieille lighthouse, which was itself then in progress. Construction began in 1887, but had to be halted quickly because the ship necessary for its construction, "La Confiance", was in use elsewhere. The works, always in summer, were resumed in 1893 and completed in 1896. The octagonal turret is supported on a cylindrical base, these two parts being mounted on reinforced concrete. The whole rises to about 9.50 meters above the highest seas. On December 4, 1896, a violent storm broke over the tower which was "beheaded".

Nature

The Raz de Sein is a stretch of water located between the Isle of Sein and the Pointe du Raz in Finistère located in the Brittany region of France. This tidal water 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. This is a very 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 recommended that heavy vessels should only attempt to cross this strait at still water during calmer conditions. The Raz de Sein is bounded by the La Vieille and Petite Vieille lighthouses and by the shoreline of the île de Sein.
