Buckingham Palace

Buckingham Palace is the official royal residence of the British Royal Family, located inside of London. It is mostly used for meetings with important people from other countries.

Palace Grounds
The palace itself and the palace grounds are very large, such that it looks like an entire section of England’s capital city was left open as a combination of two adjoining parks. There is also a square rest area that had guide lights so it could be used as a heliport to Buckingham Palace.

Hallways
The hallway was as wide as a small room. Inside the hallway were carpets meant to be looked at instead of stepped on, paintings and sculptures scattered around, and even a maid carrying around a tea set. Also, the hallway has a very tall ceiling. Much like the lights in a tunnel, shield-shaped crests were lined up on the walls at even intervals. These crests have meaning of a magical faction, so only the crests of knights were displayed. Having one’s family’s crest displayed in that hallway was the first step towards becoming a noble family. .

Meeting Room
It is a spacious area that looked more like a party hall. A number of tables were set up in concentric circles like the rings of a tree. It reminded Kamijou Touma of the UN conference room he had occasionally seen on TV.

Principles
It is used for diplomatic purposes. As such, there are no magical mechanisms meant for security measures inside the palace, despite the fact that Great Britain is a magical country. According to Kanzaki Kaori, if it was covered in magical mechanisms, it would look as if they were inviting the foreign leaders into a trap. That would be a major diplomatic problem. Also, though it doesn't have magical security measures, it is still heavily guarded by a large number of knights, magicians, and – most importantly – the queen herself.

The facility for preventing Curtana’s power from getting out of hand and creating an explosion was built into the Buckingham Palace due to the fact that the British Royal Family stays there most of the year. A subway line runs beneath the palace. A special railroad car with a magic circle on it is kept in an area branching off from the normal track. The special car is set up so it can be promptly taken to the area directly below Buckingham Palace when Curtana Original is headed out of control.
