The old port area of the French city of La Rochelle is dominated by three 14th and 15th century towers that stand tall at the entrance.
On the left you see St-Nicolas Tower, once a formidable military building. Forty-two metres high, the inside is a labyrinth of stairs and corridors. On the right, Tour de la Chaine, the oldest one, built between 1382-1390. Not shown is Tower of the Lantern.
The city was a member of the famous Hanseatic League, an economic alliance of trading cities and their merchant guilds that dominated trade along the coast of Northern Europe.
