A humungously tall tree in St Day's Old Church graveyard.

No idea what this magnificent tree is.
I have a hunch (unrelated to what the tree is), though.
Could be totally bonkers.
But here goes.
A plant specimen collector in Victorian times, and there were many who travelled the world collecting exotic specimens / seeds, died and his relatives had no idea what to do with his seed collection. So they decided to bury his collection with him (and I can't say I blame them!). And this is the result!! Look at the displaced tombstones at the foot of this tree!
