I am the sycamore with the hollow trunk. 

When younger, I had an unusual double trunk, but when the Great Storm of 1967 struck in the night, only half of me was left standing. I sealed my wounds and grew healthy new branches to balance myself. A later storm brought more of me down and tree surgery has reduced me further - but I still have a couple of healthy boughs and many vigorous branches shooting upwards. I am 'attacked' by fungi, squirrels and woodpeckers yet I am still live - with an architectural hollow trunk - and a strange bushy appearance for a sycamore. I am a survivor.

I stand on the northern boundary near the Blake's memorial.
