Ever wondered just how old a local building really is? A look at parcel records from St. Louis City, St. Louis County and St. Charles County gives us an approximate picture. Take a look at the map below to see how old parts of St. Louis are.

The above map displays the age of buildings in St. Louis City, St. Louis County and St. Charles County. Building age was determined using parcel data kept by the city and county governments. In the case of a single parcel housing multiple buildings, the age of the oldest building is displayed. The map does not represent a comprehensive picture of building age, as data for certain parcels was unavailable.
