Earlier this year Almere opened in the Weerwater a 100 meter long pier, a wooden runway made of parallel strips with up and down waves. At the end is wooden wave of 3 meters high which is also a viewpoint. The pier can be used for docking boats as part of the nearby Safety Museum as for instance police or fire boats, but it can also be seen as a self-contained piece of art.
I must admit it is a bit weird construction, to climb the wave was rather steep and didn't gave a much different view than below. The only ones enyoing the pier were the gulls and they left a lot of faeces there.
