Wonderwall
The word wonderwall is a metaphorical term used to describe a person, place, or event.

It is also a compound word.

Wonder- To be filled with admiration, amazement, or awe.

A curiosity.

Wall- Any of various permanent upright constructions having a length much greater than the thickness and presenting a continuous surface except where pierced by doors, windows, etc.: used for shelter, protection, or privacy, or to subdivide interior space, to support floors, roofs, or the like, to retain earth, to fence in an area, etc.

So a wonderwall can be widely considered as a noun that is a strong foundation full of admiration.

In other words, it is something that gives you strength.

As it is a versatile expression, it may be used as an adj.

As cliched as this is, “you are my wonderwall.”

or,

“I never realized before now, but that moment was my wonderwall.”
