Natchez On-Top-of-the-Hill Historic District
Natchez On-Top-of-the-Hill Historic District is a historic district in Natchez, Mississippi that was listed on the National Register of Historic Places in 1979.

Important sites within the district include:
the location of Andrew Marschalk's printing office, where the first book printed in Mississippi was printed in 1799, 
the first bank in Mississippi, 
the site of American flag-raising, in 1798, by Andrew Ellicott near the House on Ellicott's Hill, and
the traditional location of the earliest Sunday school south of Philadelphia, conducted at a Methodist church.

Architecturally, the district includes a set of Greek Revival works that are of national-level significance, and many other styles including Late Victorian architecture.
