Relics are mementos. It could be a piece of rock or objects of personal nature that was left behind. There are plenty of these souvenirs at work.
A brick from the demolished old building and replaced with a more elegant structure.
A century old brick used on roads.
What I enjoyed looking at is the old school chair and a rock because they are a work of art. These are relics converted to art.
The artist stands beside these artifacts and I work with her.
