Edinburgh Castle is the home to the Scottish Crown Jewels, the oldest Royal Regalia in Britain. It is also the most famous of Scottish castles. We saw 'Mons Meg' and the room where Mary Queen of Scots gave birth to James the VI and James I. A canon is fired everyday (except Sunday's) exactly at 1 pm. (1323-1357) Saint Margaret's Chapel (1285) is the oldest building in the castle. In the 12th century it was built by King David I for his mother. The great hall is the castle's main banqueting chamber. (1298) The roof is still original (16th century) and is the only piece which survived the many transformations. You see spectacular city views from the castle. Overlooking most of the city you can view the royal mile, Princess street, just to name a few.
