What is it? This behemoth in every sense is the best-known and most venerated museum in Madrid (and all of Spain). Its massive collection is housed in a gigantic neoclassical building; when it opened in 1819, the Prado became one of the world’s first public art museums.
Why go? For masterpieces by French and Italian artists, Flemish masters, and of course the Spanish, including the impressive Velázquez rooms – with pride of place going to ‘Las Meninas’ – and the Goya rooms. It’s impossible to see everything in one visit, so plan yours well, unless you’re up for spending a few days doing nothing else, which is always an option.
