Since there has been so much positive feed back about the historic structure posts, here is another structure of historic interest.
This is one of the doors to the Nassawango blast furnace, which was built in 1829. This was the work arch of the furnace, were workers would forge the iron. On the opposite site a mechanical bellows blew air into the furnace, powered by water run from the Nassawango creek. So, if there were guys making iron here, and the other side was occupied, where did the fuel and iron ore enter ther furnace?
From the top. That ramp was a charging ramp, used to roll raw materials up to the furnace in carts.
Somewhat visible at the top of the furnace from the full picture are pipes that were used to reciculate hot air from the chimney back to the air intake, making this a hot blast furnace which is much more efficient. This was a change made to the Nasswango furnace about a decade after it was built.
This is a part of the “Furnace Town” site now in Worcester, where it is accompanied by a number of living history exhibits, describing the life of a town built around a blast furnace. These are opened seasonally. However, the site contains many nature trails, maintianed by the nature conservancy, which are opened year round. You can tell it was winter when the picture was taken by the tiniest bit of snow sticking to the arch of the furnace.
