The Marlborough Cement Factory was apparently built in 1902 and was, for a time, the world's largest cement factory. Nearby, a company town sprang up that featured surprising facilities including an opera house.
On this location, the company mined and processed marl which was in that period a component of cement. When the process changed, no longer using marl, the company became unprofitable and fell into bankruptcy by 1907. By the end, the company demolished many of the building for salvage and scrap.
By the end of World War I, little more than a ghost town was left.
There wasn't a great deal left to see here, although, as I understand it, there was a bit more to be found deeper in the woods. In the brief time I was there, I had already removed a tick and decided that going further in was not something I felt like doing.
Certainly the tangible evidence doesn't point to the interesting history above, but if you happen to be in the area, it's worth a look. Watch for ticks and keep your eyes peeled for deer. There appear to be lots of both.
