Triangle Park S 4th St & Main St, Emmaus, PA18049 When the fountain is operating in warm weather months, this tiny park glistens like a jewel in the heart of Emmaus.…More Previously just a lawn with a very large evergreen tree, Triangle Park has become a centerpiece landmark. It was completely redesigned to become more resident friendly. The $305,000 project was completed in 2009. A hotel and a stable once stood on the site of the park. Borough officials promise a cut evergreen will be decorated in the park every Christmas.
