It Observatory by Robert Morris consists of two concentric earthen walls. Three v-shaped recesses have been made in these circles that provide a view of the polder landscape. The middle steel visor shows the sunrise at the beginning of spring and autumn, when the day and night are the same length. The stone wedges on either side show the sunrise on June 21 and December 21.
This is the first landscape artwork in Flevoland. It Observatory by Robert Morris was previously realized at Velsen as part of the major exhibition Sonsbeek Buiten de Perken (1971), but there it had to make way for new construction. In collaboration with the Stedelijk Museum Amsterdam, it was decided to recreate it near Lelystad, in the then extensive, empty landscape. The artwork refers to prehistoric places where the sun and planets were observed, such as Stonehenge in England.
