Madrid is a city with many attractions. Among these must-see places, there are a wide range of museums, some with great international recognition. While it is true that you have to pay some money to enjoy these museums, there is the possibility of visiting free ones on specific dates and times. It is common for some museums to offer free entry on days like 18th May (International Museum Day), or national holidays such as 12th October or 6th December.
The so-called Triangle of Art (Triángulo del Arte), which includes important art galleries such as Prado Museum, Thyssen-Bornemisza and Reina Sofia, are a major tourist attraction in the capital, with millions of people from around the world visiting them every year. Each of these important museums offers visitors the opportunity to enter them for free.
