Madrid is best known for its ‘Golden Triangle’ of art museums - Prado, Reina Sofía and Thyssen-Bornomisza. The celebrated Paseo del Arte (Art Walk) links all three. The city’s focal point remains the Puerta del Sol - the eastern puerta (gate) of the city during the 15th century. The monument of the bear and madroño (strawberry tree), in the centre of the square, symbolises Madrid. The Calle Mayor leads west from Sol, to the Plaza Mayor, which evokes the splendour of Spain’s 17th-century Golden Age.
