Longest Avenue

[shrinkingman]

Been looking around at stately homes, I wondered which of them has the longest avenue. Here are a couple to begin with. Both have avenues of about 2.5 miles, although Windor's may just be slightly longer. Anyone find a longer one?

If you notice at the Southern end of the Windsor Park Avenue, there is a statue of King George III on Horseback known as the "Copper horse"
