The Cathedral Hill Historic District is an area in Baltimore, Maryland. It lies in the northern part of Downtown just south of Mount Vernon. Roughly bounded by Saratoga Street, Park Avenue, Hamilton Street, and St. Paul Street, these 10 or so blocks contain some of the most significant buildings in Baltimore. The area takes it name from the Basilica of the Assumption which sits in the heart of the district. Despite the number of large religious structures in the area, the district's buildings are primarily commercial in character, with a broad collection of significant commercial structures ranging in date from 1790 to 1940.
