By car you can tour all six works in a day. Find them here on the map.

1. De Groene Kathedraal (1978-1996), Marinus Boezem

The Green Cathedral is a formation of 178 poplar trees, modelled on the Gothic cathedral of Reims. Dutch artist Marinus Boezem saw the cathedral as a supreme human achievement which parallels the creation of the vast Flevoland polder. Unlike a stone cathedral, this work is deliberately ephemeral, as the poplar has a short lifespan. Having reached cathedral height after around 30 years, the trees gradually die back.

Location: Kathedralenpad, Almere

2. Sea Level (1996), Richard Serra

Sea Level by Richard Serra 

Sea Level is a reminder that without the dikes to hold back the seawater, you would be out of your depth here. A wall slices dramatically into the landscape, its horizontal flatness contrasting with the grassy slope on which it stands. The top of the wall marks the level of the water before the polder was created. Sea Level is US artist Richard Serra’s largest work in Europe.

Location: Kastanjelaan, Zeewolde

3. Polderland Garden of Love and Fire (1992-1997), Daniel Libeskind

Five intersecting lines cut across the polder landscape: three narrow canals, a footpath, and a strip of black gravel featuring an aluminium sculpture. Polish architect Daniel Libeskind drew his inspiration from a poem by the 16th-century Spanish mystic Juan de la Cruz. The work symbolises imaginary connections between three cities: Almere, where it stands, Salamanca, where Juan de la Cruz studied, and Berlin, where Libeskind was living.

Location: Pampushavenweg, Almere

4. Exposure (2010), Antony Gormley

Marking the boundary between land and water, a 26-metre steel figure crouches on the dam, gazing out over the Markermeer lake. From a distance the human form is distinct, but close up the open structure becomes more abstract. British artist Antony Gormley was inspired by the steel skeletons of the electricity pylons he saw marching across the polder. This most recent of the Flevoland land art works is an impressive feat of engineering, made possible by computer-aided design.

Location: Strekdam, Lelystad

5. Aardzee (1982), Piet Slegers

Dutch artist Piet Slegers came to this location when it was only three years old, a blank, flat landscape. He created a contrasting reminder that once the land was four metres below the waves. The undulating slopes of Aardzee (‘earth sea’) are a solidified sea. The work is a dialogue between the elements of earth and water. Paths cutting through the grassy waves are covered in seashells, and in the rustle of the poplar leaves, you can hear the hiss of the breakers.

Location: Vogelweg, Zeewolde

6. Observatorium (1971-1977), Robert Morris

Observatorium is like an ancient monument in a new landscape. Grassy banks form two concentric rings, bisected by a path leading to an enclosed inner circle with a mysterious acoustic. Two giant V-shaped openings cut into the outer circle. The ideal time to visit Observatorium is at dawn on the summer or winter solstice, when the sun rises precisely in the centre of the northeast or southeast opening respectively. US artist Robert Morris was inspired by prehistoric megalithic works with solar alignments, like Stonehenge.
