Edinburgh Castle of Scotland, UK (蘇格蘭愛丁堡城堡)

From its position on top of an extinct volcano (aptly named Castle Rock), Edinburgh Castle literally cannot by anyone in Edinburgh. The iconic sprawling fortress can be seen from anywhere in the city center. Its prominence means that it has been often been targeted throughout its history, including during the Wars of Scottish Independence and the Jacobite Rising. It was a royal residence since at least the 12th century, during the reign of David I, until 1603 with the Union of the Crowns. It then acted mostly as a military base in the 17th century and is still technically owned by the Ministry of Defense. The annual Edinburgh Military Tattoo is held here, and the castle now is Scotland's most-visited paid attraction.
