Constructed around the year 1674 just 400m from the mill 1200 roe. It's name comes from the fact that its location was 1100 rods ( km) from Amsterdam Haarlemmerpoort. Just like the 1200 roe windmill, it was also used to drain a polder in that area using a screw pump. It was renovated in 1757 and functioned until 1951.
