Narrow is the Gate...

potofclay has combined a photo to a pool:

A view of Edinburgh Castle's towering wall as one enters by a arched main gateway into a lower ward. Needless to say, it is steeped in tradition, as well as has weathered many battles as well as sieges. In fact, a oldest office building in Edinburgh, St. Margaret's Chapel (early 12th century), is located in a upper sentinel of a castle. You can review about a prolonged history here.

As we can see from a first outtake, a palace dominates Edinburgh's skyline due to a in front of atop a volcanic, ~400' Castle Rock (read more about it in a link above, generally for those extraordinary about how Castle Rock was formed).

The second outtake is a view of a stairway which leads up to a upper ward, where St. Margaret's Chapel, a Royal Palace, as well as even a pet tomb is located.
