An art work by Heinz Mack, installed for the winter beside the lake of St Moritz:
850 000 mosaic gold plated tiles
50 tons
7.5m high

They are possibly more impressive when lit up at night, but I enjoyed reading all about them whilst walking Piper around the lake in the fresh snow and waiting for M to come out of the klinik after seeing a knee specialist.
