This 360º Panoramic Tour starts in the Great Hall, and allows you to travel out into the Castle Courtyard (try clicking on the door at the far end of the hall to the left of the table).

The panorama above is interactive.

Try clicking with the mouse and dragging left or right.  The image will rotate through 360 degrees.  You can zoom in by pressing the left shift key, and out by pressing the Ctrl key.
