Senior Hall, Rustic architectural building in California, United States

Senior Hall is a building with rustic architectural elements located in California and listed on the National Register of Historic Places. The structure displays handcrafted details from traditional construction methods visible in its exterior and interior framework.

The Order of the Golden Bear, a senior honor society, proposed a meeting hall for senior men in 1905 and raised private funds to build it. John Galen Howard designed the log cabin pro bono, and it was dedicated on September 19, 1906. It served as the university's student union until a new union replaced it in 1923. Threatened with demolition in 1973 to expand the Faculty Club, it was preserved, listed on the National Register of Historic Places in 1974, and reopened in 2021 after renovations.

The Order of the Golden Bear, a senior honor society, raised the money from private donors and still meets here; the hall's hidden chamber, entered through a concealed door, holds a redwood "throne" and amber-glass windows. Female students were barred from the hall in its early years.

Senior Hall stands on South Drive in a redwood grove beside Strawberry Creek on the UC Berkeley campus. It is a one-story cabin of about 3,168 square feet, closed for years before reopening in 2021, and used by the Order of the Golden Bear, so it is best seen from the outside; look for the large oak door and the bark-covered logs.

Inside, a hidden chamber for the Order of the Golden Bear has no visible entrance when closed; its casement windows use amber glass, and the room holds a "throne". The main room's brick fireplace carries a cornerstone dated 1905, and the redwood furnishings are original.
