How old is this creeper?

The two photos show the same building, one covered in Virginia creeper, the other recently cleared. The building is 545 years old and currently used as a tea room. Upon removing the plant cover, there was very little actual damage to the building.

As part of maintenance, the building is stripped of climbing plants periodically. So can you guess when the last clearance was? That is how many years' growth.
