If you can handle the crowds (maybe May, when I came, is just an extra busy time of year?), this is a wonderful place to wander for a few hours. There are lots of things to do within the castle walls, including smaller museums like the prison museum (complete with some fascinating historic graffiti) and the Scottish Crown Jewels, and a cafe and tea house. Plus plenty of spots to take photos of the amazing views of the city below. An afternoon well spent.
There has been a royal castle on the castle rock since the 12th century. As one of the most important strongholds in the Kingdom of Scotland, it has been involved in many conflicts from the Wars of Scottish Independence in the 14th century to the Jacobite rising of 1745. There have been 26 sieges of the castle in its 1100 year history, making it the most besieged place in Great Britain and one of the most attacked in the world. It is now the second most popular tourist attraction in Scotland, after the National Museum, with 1.78 million visitors in 2017
The most dominating part of the Edinburgh Skyline. Edinburgh Castle sits atop a cliff over-looking the city at one end of the royal mile. The castle has been such a big part of the history of the city and the history of Scotland as a whole. From iron age hill fort to medieval castle, this place has a ton to see and do.
Spectacular views of the city from ramparts of the Castle. Not to be missed
A tourist masterpiece. It is not only in the center of the city, it is basically the emblem of it and shapes the whole area. A must-see!
