 Like other so-called "trolley parks" of its era, Norumbega Park became popular with the increasingly urbanized, middle class population who sought affordable recreation outside the city environment.By the 1905 season, the outdoor theater at Norumbega Park was replaced by a luxurious enclosed facility called the Great Steel Theater.The new venue featured vaudeville acts, plays (dramas, comedies, and musicals) as well as moving pictures shown on a novel device called a "Komograph".
