Central Troy Historic District

The Central Troy Historic District is a protected area in downtown covering over 700 buildings from the early 1800s through the mid-1900s. The architecture shows different styles and construction methods that developed over roughly 150 years and reflects how buildings changed throughout that time.

Two major fires in the 1800s forced rebuilding efforts that introduced stricter building rules. These fires shaped how the district looks today and determined how many of the structures standing now were built.

Washington Square mirrors the design of British residential squares and creates its own character in the middle of the city. The street layout reflects Philadelphia's urban planning approach and shapes how the district feels to walk through.

When exploring, watch for different building types and their details to discover the range of construction styles. A leisurely walk through the streets lets you take in the facades and architecture from different angles and understand how the district is laid out.

The name 'Collar City' comes from this district being the center of making detachable shirt collars, which Hannah Lord Montague invented. This simple invention turned Troy into the heart of a major industry that drew thousands of workers.
