A favourite tree

I love trees and this one is in a neighbour's garden diagonally from us, the sun was hitting the trunk beautifully back in April and then you can see it now in full Summer leaf. I love the sound of the wind rustling through, it reminds me so much of the ebb and flo of the sea, such a peaceful, tranquil sound. I've no idea what sort it is but so happy we live by it :)
