Madrid is surrounded by beautiful mountains and other cities and towns with historic interest providing ample opportunity to take a day away from the hustle and bustle of the urban jungle and appreciate some less crowded locations. Sierra Madrid: the mountains of Sierra Madrid lie to the north of the city and are a haven for those who enjoy walking, hiking or climbing. The mountains can be reached easily from the city and are a popular retreat for the locals, providing a welcome escape from the urban jungle. Alcala de Henares: visitors head for Alcala de Henares for its historical interest, much of which surrounds the university that has been there since the late 13th century. Known as the Complutense (a name taken from the Roman town Complutum), the university was once one of the most important in the world. The university offers some fantastic architectural views with its magnificent Renaissance facade, among the most famous. Aside from the main university buildings, visitors should check out the old student residence buildings (Colegios Mayores). Breaking the continuity of the wall at one point is a cathedral which was begun in the 12th century but actually not completed for almost 600 years. Beyond the city wall lies the Basilica de San Vincente, another interesting structure that was built between the 12th and 14th centuries, allegedly on the site where Saint Vincent and his sisters were martyred. Aranjuez: a train ride from Madrid's Atocha station brings you to Aranjuez, a small town with an interesting mix of both lush greenery and arid landscape. The town’s main visitor interests include the Casa del Labrador (Labourer's Cottage) and the 18th century Palacio Real (Royal Palace). There are also some fine gardens that are well worth a visit with the Jardin del Principe (Prince's Gardens) standing out as one of the most notable. |
