This complex has been occupied since 1847 and prior to the foundry's closing in 2002, it was the oldest continually operating malleable iron foundry in America. My trip to the complex last October was my first exploration since 1997. I was leery of going inside and limited my exploration to the grounds. Last week, I returned and explored the interior. Here are the links to the two blog posts I wrote about this place:
