The original Washington Water Power Company Steam Plant , built in 1907 (on the site of a water power facility built in 1892).
The site is still owned by Washington Water Power Company (founded 1873), which has operated since 1998 as Avista Utilities. Part of the complex still houses some of Avistas offices; with other offices, shops, and food service, in the remaining space.
The main restaurant area is built around the original coal elevator, and some of the original powerplant machinery (and much of the piping, catwalks etc...); which have been preserved, and placed on display for patrons to see. It's a fascinating place to have dinner (and quite a good restaurant, though a bit pricey).
