Dung heaps serve as reminder of Nazi past

Visitors to Berlin's main modern art museum this summer should take care not to step on piles of horse manure, placed as a reminder of art that was stolen, destroyed or went missing under Nazi rule.

With his installation at the New National Gallery of four piles of artificial dung, painted blue, Austrian artist Martin Gostner has said he is paying tribute to Franz Marc's painting "The Tower of Blue Horses."
