Edinburgh has more museums per capita than almost any city in the UK, and a startling number of them are free. The National Museum of Scotland alone could swallow an entire day. The Scottish National Gallery has a Vermeer. The Portrait Gallery building is so beautiful that people sometimes forget to look at the art inside it. And then there are the stranger ones: a museum of surgical instruments where the exhibits include real human specimens, a 17th-century street buried beneath the Royal Mile, and a concert hall from 1763 that most Edinburgh residents don't know exists.
This is a city that was the centre of the Scottish Enlightenment, a place where David Hume, Adam Smith, and Joseph Black were neighbours. It holds UNESCO City of Literature status and the world's largest annual arts festival. That intellectual history shows up in the museums. Even the quirky ones have depth. Even the free ones feel properly funded. Edinburgh takes its cultural institutions seriously in a way that translates directly into the visitor experience.
This guide covers 15 museums and galleries, from the major nationals to the smaller collections that most visitors walk past. Eight of them are completely free. If you're planning a rainy day (and in Edinburgh, you should plan for several), you'll find enough here to fill a week.
