Castle Howe, Kendal, Cumbria.
This is probably the site of a 12th century motte and bailey castle. A wooden keep built on the motte (mound) would have been surrounded by the bailey (a fenced yard). The remains of the slightly later Kendal Castle can be seen across the town from Castle Howe.
The 1788 obelisk on the top of the motte was erected as a celebration of the Glorious Revolution of 1688 (the arrival in England of the protestant William of Orange and the abdication of the hated Scot, James 11).
