It's easy to like Rittenhouse Square and the American Planning Association agrees.
The educational and professional organization has designated the square - one of the original five squares in William Penn's "Greene Countrie Towne" - as one of nation's top 10 great public spaces for 2010.
The APA said it singled out Rittenhouse Square because of the long-standing tradition of residents maintaining the park.
"We're very excited to name Rittenhouse Square as one of this year's great public spaces," APA Chief Executive Officer Paul Farmer said in a statement. "For Philadelphians and tourists, Rittenhouse Square is a true landmark. City officials and residents have done a spectacular job in carrying out William Penn's original plan for their city and keeping Rittenhouse Square a remarkable public space."
