Society Hill is loosely defined as the area between Walnut, Lombard, Front and 8th streets. According to A View on Cities, it contains the "largest concentration of original 18th and early 19th century architecture of any place in the United States."
An example of this old architecture is the Society Hill Synagogue. It was built in 1829 as a Baptist Church by one of the architects who worked on the Capitol building in Washington, D.C. St. Peter's Church, another interesting building, was constructed between 1758 and 1761.
This area of the city is close to the river and Independence Hall. Besides churches, it contains market halls, taverns and brick houses.
