Philadelphia (pron.: /ˌfɪləˈdɛlfiə/) is the largest city in the Commonwealth of Pennsylvania, the second largest city on the East Coast of the United States, and the fifth-most-populous city in the United States. It is located in the Northeastern United States along the Delaware and Schuylkill rivers, and it is the only consolidated city-county in Pennsylvania. As of the 2010 Census, the city had a population of 1,526,006, growing to 1,547,607 in 2012 by Census estimates. Philadelphia is the economic and cultural center of the Delaware Valley, home to over 6 million people and the country's sixth-largest metropolitan area. Within the Delaware Valley, the Philadelphia metropolitan division consists of five counties in Pennsylvania and has a population of 4,008,994. Popular nicknames for Philadelphia are Philly and The City of Brotherly Love, the latter of which comes from the literal meaning of the city's name in Greek (Greek: Φιλαδέλφεια ([pʰilaˈdelpʰeːa], Modern Greek: [filaˈðelfia]) "brotherly love", compounded from philos (φίλος) "loving", and adelphos (ἀδελφός) "brother").

A facade or façade (pron.: /fəˈsɑːd/) is generally one exterior side of a building, usually, but not always, the front. The word comes from the French language, literally meaning "frontage" or "face".

In architecture, the façade of a building is often the most important from a design standpoint, as it sets the tone for the rest of the building. Many façades are historic, and local zoning regulations or other laws greatly restrict or even forbid their alteration.
