It may not be as old and famous as the London Underground or the Paris Metro, but it's new, fast, useful and very-very clean! It started in January 2000, after so many problems with excavations, due to antiquities found under the ground. The Metro tunnels were constructed at a depth of 15 meters, a level which is much lower than usual. There are 31 stations and new lines are designed for the coming years.
