According to tree specialist Charlier, the owner of the neighbouring domain "Closerie du Rond Chêne", this tree was planted in 1891 by gardener Léon Crépin, which means that the girth of this tree has increased about 8 cm yearly on average.
The tree maintains its large girth near the bottom up until a quite large height, which makes it probable that this giant sequoia is the most voluminous tree in Belgium. I estimate the volume myself at about 96 m³. If correct, then this tree is by far the tree with the most voluminous trunk in the Benelux.
The girth of the tree is 9.15 m measured at a height of 1.50 m (Nov 1, 2011, BELTREES). Its height is around 36.00 m (2006, measurement method unknown, Nardo Kaandorp). This tree was planted in 1891, which makes it exactly 122 years old (BELTREES, Oct 1, 2011).
