<\/a>Did Aliens create this? (Image: Google Maps)<\/p><\/div>\n
It is a bit weird. There are roads all around that hole, and even some buildings it seems.<\/p>\n
What is that weird round eye right in the Ketelmeer<\/em>\u00a0between the two parts of the Dutch province Flevoland?<\/p>\n For other posts in the series Strange Places<\/em> in the Netherlands, click here.<\/strong><\/a><\/p>\n It is much less scary than it seems. This island is called the\u00a0IJsseloog\u00a0<\/em>(IJssel Eye), as the round shape reminds of an eye, and it is located at the estuary of the\u00a0IJsselmeer<\/em>, the huge lake in the middle of the Netherlands, closed off by the Afsluitdijk from the North Sea.<\/p>\n As you may guess now, this Island did not come into being naturally. It is\u00a0pushed up\u00a0ground, made\u00a0artificially, something the Dutch are masters at. Much of the ground of the Netherlands nowadays had been underwater before. The entire province of Flevoland is actually created by this method. More on that in another post to come!<\/p>\n So why this IJsseloog?<\/strong><\/p>\n Well, first and foremost it serves quite an important\u00a0purpose: catch all the water that is polluted with slib <\/em>(sludge). Slib\u00a0<\/em>is a sediment in water, which was already used by the Egyptians to fertilize their lands. In the past decades, however, that\u00a0slib\u00a0<\/em>has been polluted with heavy metals.<\/p>\n Rijkswaterstaat\u00a0<\/em>(Dutch Ministry of Infrastructure and Environment) was concerned about this pollution, as it wanted to prevent this pollution of spreading throughout the IJsselmeer, and kill fish, get into water used for agriculture and other uses (the IJsselmeer holds fresh water!).<\/p>\n Cleaning the slib is too cumbersome – and therefore a permanent deposit was needed.<\/p>\n This is the\u00a0IJsseloog.\u00a0<\/em>You may wonder why it was not just created on land, but this decision was made to prevent contamination with water that farmers use, and to prevent water to drain there. And in the water the Dutch found a smart solution to keep the\u00a0slib\u00a0<\/em>from mixing – and it is a typically Dutch solution!<\/p>\n
