It’s Amazing That A Tree Can Grow Through Centuries-Old Brick Walls
The tree most likely started growing at the same time that the gate was constructed, but because it saw the wide space that existed between the walls as being unsafe, it felt the need to fill in the space. At this point, there is no way for anyone to scale the walls and illegally enter the Putzar castle grounds.
It is amazing that a tree can grow around or even through brick walls that were constructed hundreds or even thousands of years ago. They are so powerful, and nature is pretty resilient as a result of the fact that they can establish a home for themselves and put down roots wherever they require.
