Built in 1885, the original Opera House burned down in the 1892 fire that destroyed much of downtown Woodland. It was rebuilt on the same site, using some of the remaining foundations and bricks from the walls, reopening in 1896. Today, the interior of the Opera House has been painstakingly restored to the grandeur it enjoyed at the turn if the century. Careful attention was paid to reproduction of the wallpaper friezes, paint colors, and carpeting. The main floor carpet was manufactured in England and shipped to the Opera House for installation. Comfortable main floor theater seating was built on the East Coast for installation and the historic pew-like benches in the balcony area were repaired or carefully replaced.

The Trading Post site also houses Gray Gables Railroad Station, built for the personal use of President Grover Cleveland during the years of his presidency (1893–1896). The Greek Revival-style Briggs-McDermott House has been restored and furnished to reflect the period from 1840 to 1910, an important time for the Briggs family and Bourne.
