This remarkable, and completely hollow, sessile oak (Quercus petraea) is located in Cowdray Park, West Sussex ([map](https://www.monumentaltrees.com/en/map/gbr/england/westsussex/975_cowdraypark/1738/)). Queen Elizabeth I sat under this tree in 1591, the tree was unlikely to be hollow then but still nearly 500 years old. More infomation can be found on [monumentaltrees.com](https://www.monumentaltrees.com/en/gbr/england/westsussex/975_cowdraypark/1738/) I have removed the fence from the model, but please if you visit, don't get too close :)
