Philadelphia is known for its arts and culture. The cheesesteak and soft pretzel are emblematic of Philadelphia cuisine, which is shaped by the city's ethnic mix. The city has more outdoor sculptures and murals than any other American city, and Philadelphia's Fairmount Park is the largest landscaped urban park in the world. Gentrification of Philadelphia's neighborhoods continues into the 21st century and the city has reversed its decades-long trend of population loss.
