It is a playground for old and young: the National Museum of Scotland or Royal Museum in Edinburgh, Scotland is a fantastic museum of natural history, technology and art. It is not the biggest one I’ve ever seen but it consistently includes elements to play and have fun. It was opened in 1888 and can be visited free of charge.
In fact the National Museum of Scotland and the Royal Museum were two stand-alone museums next to each other and were combined in 1998. The permanent exhibition includes items about geography, archaeology (e.g. Egypt), technology (e.g. planes, robots), art and natural history (e.g. animals). But there are also always special exhibitions changing over time. It is a nice plays to spend time, the architecture is great and they serve fantastic cake.
