What is it? Only the finest museum in the entire city
Why go? The National Museum in Cardiff is equal parts explorative adventure and artistic showcase, with exhibitions showcasing everything from botany to zoology, found rooms away from one of the best collections of modern art in Europe. The museum tells the story of Wales from the Big Bang to the Red Wall, covering a huge amount of ground with character and style. The museum is also free to enter, although do leave a donation if you can.
