Description.
The Petaluma and Santa Rosa Railway Power House is a single story building constructed of locally quarried stone. It is L-shaped, with a tile roof. Since the dissolution of the railway company, the building has housed a number of private business, including a series of brew pubs. The current owner, Hopmonk Tavern, removed a non-historical deck surrounding the east and west ends of the building, returning it to its historical profile.
