Man Watches Strange Lump On Tree Grow For 20 Years — Then He Opens It

Preserving the oak

The oak tree itself was carefully preserved. Harold had the opening sealed properly with the help of expert arborists. The bunker beneath was emptied and turned into a small private museum. Harold added a memorial plaque at the entrance honoring Mr. Fulton’s work. The bulge on the tree remained as a permanent reminder of the past.
