In 1683, Thomas Holme mapped out the streets of Philadelphia in a grid with streets running East to West perfectly. Because of this, the sun rises every morning and East, West, North, and South can be clearly differentiated on the grid that makes up Philadelphia. The name of the Philly henge goes all the way back to 2600 B.C. when people built the stone henges for the sun. These monuments were a means of registering the universe and their place in it.” (Burlando) Stonehenges were meant to align with the sun’s arcing trip through the sky. So on certain special days, Philly will turn into a sundial and register the passing of another year.
