Workers on Tuesday posted a huge sign on the side of Lafayette College's newest arts building.

William C. Buck Hall is the final piece to the Easton school's $21 million arts campus going in on North Third Street, at the foot of College Hill.

Buck Hall will house a 200-seat black box theater and an 180-seat film-screening room. The 18,000-square-foot building contains a box office, control room, smart classroom, dressing rooms, and scene and costume shops.

The film and theater departments occupy the college's building across Third Street, which opened in January 2015. The building is expected to open in early September.

The hall was named for William C. Buck, a 1950 alumnus who made a major contribution to the school, according to the Lafayette website.
