Logan Circle, also known as Logan Square, is an open-space park in Center City Philadelphia's northwest quadrant and one of the five original planned squares laid out on the city grid. The circle itself exists within the original bounds of the square; the names Logan Square and Logan Circle are used interchangeably when referring to the park. The park is the focal point of the eponymous neighborhood.
Originally called "Northwest Square," the park was used for public executions and burial plots until the early nineteenth century. In 1825, it was renamed Logan Square after Philadelphia statesman James Logan. In June 1864, temporary buildings were built on the square and it was the site of the Great Sanitary Fair, a 2-week exposition that raised US$1,046,859 to buy medicine and bandages for Union troops during the American Civil War. President Abraham Lincoln visited the fair.
Traditions: To commemorate the end of every school year since the 1960s, the newly appointed Sophomores, Juniors, and Seniors of J. W. Hallahan Catholic Girls High School jump into the fountain. The event is the subject of much local Media coverage throughout Philadelphia.
