Peirce Mill

Peirce Mill is a three-story stone mill in Rock Creek Park that used water power to grind grain. The building houses millstones and gearing systems that demonstrate how grain was processed into flour during the 1800s.

The mill was built in 1829 and operated for more than 60 years as part of Washington's early industrial development. It became inactive in the late 1800s when the machinery needed for continuous operation failed.

The mill reflects how communities depended on water power to process grain, a crucial part of daily life in early Washington. Walking through it, you can see how industrial work was organized and what milling meant to people living nearby.

The site is located within Rock Creek Park and is accessible by walking trails that lead through the park area. Visitors should be prepared for stairs and confined spaces inside the building when exploring the machinery and different levels.

The mill was designed using advanced automation techniques that were uncommon in early American industry, showing how machinery could work together efficiently. Today, demonstrations reveal the clever engineering that made grain processing faster than traditional methods.
