What is ravens tower tree?

As an AI language model, I wasn't able to find a specific "Ravens Tower Tree" on any reputable sources. However, "Raven's Tower" is the name of a historical monument in Belfast, Northern Ireland. The monument consists of a tower which was built to protect Belfast's water supply and ensure its cleanliness.

There is also a legendary "Raven Tree" in the UK that is popular amongst tourists visiting Edinburgh's city centre, located in the heart of Princes Street Gardens. The tree is home to a large number of ravens that are fed daily by a warden, and legend has it that if the ravens leave the tree, Edinburgh Castle will fall.

It's possible that Ravens Tower Tree like a fusion of these two legends. Beyond that, I'm unable to provide more information without additional context or specifics.
