A hidden treasure

Took this photo a few days ago, while on one of the first warm spring walks by the river.

Doesn't look like something that is considered one of the most valuable treasures of the world, does it?

What I tried to capture on this photo is one of the oldest vines in the world.
Yp, situated in the heart of my town, Maribor.
