Have you noticed something bizarre on the 21st of June in Greenwich? Did you see two cows in the grass outside of the Old Naval College?
Well, you weren’t dreaming. This really happened. These cows were part of an art installation (created by Captain Boomer Collective, a Belgian group).
A massive frame fenced the cows and people could sit there and enjoy the interesting scene.

The reason for this was artists trying to recreating scenes from Victorian landscape painters in real life.
