Echo Park Entrance
In the early 20th century the Chautauqua site was turned into an amusement park named Glen Echo Park. The amusement park was one of the larger establishments of its type in the Washington, D.C. area, and was very popular well into the late 1940s. By the mid-1950s, however, attendance began to decline due to the growing popularity of larger regional theme parks, such as Disneyland. Another blow to the park occurred in 1960 when the trolley line from Washington, D.C. ceased operation.
