Later this month the new 9.7 km North-South metro line in Amsterdam will start service. Like most large scale infrastructure projects, its opening has been delayed many times. 8 times according to this source. But this post is not about that. It’s about a byproduct of the line’s construction.
The excavations required for the line meant that two sections of the Amstel River – namely the Damrak and Rokin sites – had to be drained. This took place from 2003 to 2012 and gave archaeologists unprecedented access to the bottom of a river in the middle of a historic city center.
Amsterdam started as a small trading port along the banks of the Amstel River some 800 years ago. So not surprisingly, they found a few things. Over 17,000 objects were found and all of them have been catalogued online according to time period, use, material, and location found.
