The foundation of Robbins Mill is part of the Trail Through Time.
The dams and sluiceways show remnants of industry along Nashoba Brook. Nearby is the Wheeler farm foundation, recently restored as an example of old stone foundation work. Nashoba brook was a source of power for Robbins mill and, further downstream, a pencil factory. The nearby trails highlight several other historic sites including a Native American stone chamber and stone piles and a colonial era foundation of a "pest house" used to quarantine people outside of population centers.
