Artist Marc van Vliet is the creator of Drie Streken – or ‘Three Zones’, featured in the Oerol Festival, 2016.  It is a floating, wooden observatory in the Dutch flatlands, in the north of the Netherlands.
Placed at the meeting of compass points which are illuminated by the passage of the sun, it is an observation post reached via a long wooden platform.

The structure was designed to be placed in different parts of the flatlands of the Frisian coast, over four years and to be viewed in the context of ‘Sense of Place’ – a celebration of the vast expanse of the Northern flatlands.
