Beech grove, Dyrehaven (Deer Park) in Vejle, Denmark, originally created for hunting purposes and now popular in Denmark as nature sanctuaries in the cities.  Some of the last remaining places in Northern Europe to find old growth trees, as logging has been a main industry since the 9th century and although they practice reforestation, it's just not the same is it?

While in Ireland we were quite honored to spend the day with the Earl of Longford, Thomas Packinham, who has been collecting and planting species of trees on his family estate for the past 50 years.  His gardens are exquisite and he had an encyclopedic knowledge of all things trees.  A real kindred spirit, he's traveled all over the world to photograph trees and uncover their stories and has written 4 books on his findings.  We could hardly keep up with him as he led us through the arboretum (and yes, past his giant castle!)
