These spiky looking red things are “anti-tank hedgehogs” just outside of Moscow. They are designed to be placed in roads or along defensive lines to stop mobile armour zooming about. These hedgehogs are a memorial that marks the closest point to Moscow reached by the German armour in the winter of 1941. That huge car park and building to the south-west is bizzarely an Ikea store. There is some concern about future construction and its proximity to the monument.
