Located in almost the centre of Spain, is Madrid, the capital

The city has preserved the look and feel of its historic neighbourhoods and streets.

The Madrid Metro is one of the largest metro systems in the world, which is especially remarkable considering Madrid's population is approximately 3.5 million.

The first line of the Madrid metro opened on October 17, 1919 under the direction of the Compañía de Metro Alfonso XIII, with 8 stations and 3.5 km. of track.

When the trains come into this station, the mural moves, and show an animated train rolling across the wall.

Stations in the Madrid metro reveal their age in their design: older stations on the narrow lines are often quite compact, rather like the stations on the Paris Metro. They were decorated with tilings in different colour schemes depending on the station.
