Edinburgh Castle stands tall at the center of the city atop an extinct volcano. The castle on top of the cliffs is imposingly magnificent. A witness to Scotland's long history, it has served as a royal residence, a military fortress and even a prison. In later eras, the king began to renovate the castle into a residential palace. Currently, the oldest extant part of the building is a small chapel which was built in the 11th century. It can be said that Edinburgh Castle is at the core of Scottish national history. On display in the castle you can see the Scottish crown jewels and the famous Stone of Destiny. Historically, Scottish royalty sat on it during their coronation ceremony.
