Edinburgh castle is rich with history and from it's position on castle rock you can see how imposing this fortress is.
My family and I toured the castle with a guide and it was an unforgettable experience. There has been a castle on this hill since the 12th century & the castle was used as a home for Royals until 1633.
The Scottish crown Jewels (The crown, Sceptre, and Sword of State) are in Edinburgh Castle.
I recommend a visit to Edinburgh Castle and if you don't care much for history or castles they also have plenty of whiskey tours in Edinburgh ;)
