The structure was closed to the public in 2011 for safety concerns, but had previously been a tourist destination. It stood nearly 100 feet tall and had 10 stories that spread across seven trees, complete with balconies and staircases.

Though the structure has been officially closed for many years, it was allegedly trespassed frequently by vandals.

The investigation into the cause of the fire is ongoing, Cumberland County Fire/Rescue officials said.
