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. Originally called ''Northwest Square,'' the park had a somewhat gruesome history as a site of public executions and burial plots until the early Nineteenth Century. In 1825, it was renamed Logan Square after Philadelphia statesman James Logan.
