Ladies and gentlemen, it is time to get down and dirty. Nope, this article is not about lesbians. This dyke is not made of flesh and bones, but it is made of dirt, dung and, ok probably 'bones'. This dyke is actually an old Route 66.
A dyke is an artificial slope to regulate water levels, also called levee in American English.
This particular dyke is old. Very old. It has been build roughly between 1000 and 1300 AD. Yes, sure, there are dikes dating back from around 0 AD. But this one is still intact. It saved our ass until 1825. Besides, it is the best introduction of understanding what the heck a dyke is for.
The name is this dyke is the Slachtedyk. The word 'dyk' is the Frisian word for "dyke". Let's leave out the word 'dyk' and have a closer look at 'slachte'. This might give us a clue what the dyke was really about.
There has been some research about the name. A very plausible translation for the old word 'slachte' is 'part'. It is related to the English word of 'slaught', cutting up meat into parts -or enemies for that matter. That is exactly what it was. Slachtedyk was a dyke that consisted of several parts. Different parts of the dyke fulfilled different functions over the hundreds of years.
What makes this dyke so special is that if you walk on it, you will be able to see the two different functions a dyke had. You need a sharp eye. And photo’s normally do not show it due to loss of perspective and depth. So you really need to see it with your own eyes ;-)
The first function was as a sea dyke, protecting us from the high floods.
The second function was a polder dyke. It was to gain land, a very peaceful way of annexing land without going to war.
As to the second function: remember, we created our own land, while God created the earth. The procedure is simple. Create a dyke around a lake, wetland or marsh, put windmills on the dyke and pump the water out. Voila, there you have your new land. Looking at the map, you will even find a place called 'New land' or 'Nijland'.
The Slachtedyk has never been build as one dyke from scratch. It is a collection of dykes, both sea dykes and polder dykes, being connected over time. Have a look at this time-lapse animation below.

The result of linking all the dykes allows for people to travel easy and quickly from one side of the country to the other. Just like route 66 connects Chicago, Illinois with Santa Monica, California (West coast).
The dyke measures somewhere around 42 kilometers. I know what you think. It is ideal to make a marathon out of it. The Frisians thought so too. Every 4 years you can join the marathon.
But, every day you can walk the Frisia Coast Trail ;-) It will take you two days walking from Raerd (Rauwerd) to Easterbierrum (Oosterbierum) at the Wadden Sea coast. This stretch is covered when hiking stage 4 of the Frisia Coast Trail.
