On the way across the moat, I paused to take a photograph of the view over Salisbury:
The castle dates from around 1070, and was built on the earthworks of an Iron Age hillfort, although most of the stonework that remains dates from the 12th and 13th Centuries:
Only the flint cores of the walls remain in most places; they would once have been faced with flat stone:
From the castle, it is possible to look out over the remains of the cathedral and bishop's palace, the latter built by Roger of Sarum in spite of his having a perfectly good house inside the castle:
The castle is also close to Old Sarum airfield and we saw lots of planes flying overhead, as well as this lot floating around beyond the trees (click on photo to see them properly):
The whole place is well worth a visit.
