The Cottrill Opera House in Thomas, West Virginia, designed in 1902 by Holmboe and Lafferty. In 1940, the top of the facade damaged and stuccoed afterwards.

Hiram Cottrill, a proprietor, came to Thomas in 1887 and was a mine superintendent at the Davis Coal & Coke Company before launching a career as an impresario. The theater closed in the 1970s and is being restored after years of neglect.
