Sylvan Grove Theater and Columns, Outdoor theater with Ionic columns at University of Washington, US.

Sylvan Grove Theater is an outdoor theater on the University of Washington campus in Seattle. Within it stand four 24-foot (7.3 m) Ionic columns made of hand-fluted cedar, saved from the university's original downtown building of 1861. The columns are arranged in a grove, with grass seating on the sloped ground around them.

The four columns came from Washington Territorial University's first building erected in 1861. They were moved to this location in 1921 following a student design competition.

The four Ionic columns are named Loyalty, Industry, Faith and Efficiency; their initials spell LIFE. University Comptroller Herbert T. Condon and history department head Edmond S. Meany gave them these names. The columns are hand-fluted cedar from the first university building, and the site has drawn the attention of paranormal investigators.

This venue is freely accessible year-round and serves as both a quiet retreat and gathering space depending on the season. The sloped terrain means sturdy walking shoes are helpful, especially during wet weather when grass can become muddy.

The columns are hand-fluted cedar, carved for the territorial university building that opened on September 16, 1861. When it faced demolition in 1908, Edmond S. Meany had them saved; they stood in the Quad from 1911 to 1920 before reaching Sylvan Grove in 1921.
