Philadelphia is a huge city with several district articles containing sightseeing, restaurant, nightlife and accommodation listings — consider printing them all. Philadelphia, located in southeastern Pennsylvania, on the southern fringe of the mid-Atlantic region, is the fourth-largest urban area in the United States and the country's sixth-largest city. Often referred to as "Philly," the city's metropolitan area encompasses twelve counties in Pennsylvania, New Jersey and Delaware. Philadelphia, often called the "Birthplace of America" and referred to as the "new Athens" early in its existence, is the birthplace of America's modern democracy. Founded by William Penn in the late 17th century, the city's name translates to "City of Brotherly Love" and has been a seat of freedom since its inception; originally founded by Quakers, the colony promoted religious freedom among its residents in stark contrast to the England of the time. Philadelphia falls in the northern periphery of the humid subtropical climate zone. Summers are typically hot and muggy, fall and spring are generally mild, and winter is cold.
