Riverton Park casino in Portland. The park was developed by the Portland Railroad Company in 1896 as a popular day-trip destination via trolley. The park offered a variety of amusements, including a dining hall, theater, boating facilities, a small zoo, and a midway. An advertisement for entertainment in July 1897 featured Alabama troubadours, buck-and-wing dancers, the Jubilee Singers, plus a "balloon ascension and parachute adventure with Monsieur Roberto, Meteor of the Sky!". The casino was demolished in 1933 after several years of inactivity.
