The Riverton Park, which was owned and operated by the Portland Street Railroad Company, was opened in 1896 in Portland.

The Casino was the most popular attraction at the Park. In addition to card, reading and smoking rooms, the Casino had a dance hall and a theater that seated 2,500 people. Vaudeville shows were performed there every afternoon and evening. The Orchestra also played every afternoon and evening, with special performances on Sunday afternoons.

The grounds of the Park were popular and featured many different outdoor activities. There was a Canoe house with an electric launch. Visitors could also enjoy the many animals, both large and small, that were kept in the Park. There was a trout pond, in addition to many boiling springs that provided drinking water to the Park.
