Strengthening the historic setting of the St. Louis Place neighborhood’s dense core, now nominated to the National Register of Historic Places as a historic district by the Preservation Research Office, are remaining parts of the built environment beyond buildings. There are several remaining brick alleys and historic granitoid sidewalks on and around St. Louis Avenue between 20th Street and Parnell Avenue.
If the word “granitoid” is not familiar, the appearance probably is. Granitoid sidewalks included crushed aggregate rock in the cement to create a speckled walk with the surface appearance similar to granite. Granitoid paving dates to the 1890s and was common through the early part of the 20th century. Contractors often left a metal plaque embedded in the pavement to identify their work. St. Louis Place is fortunate to not only have these plaques left, but to have hundreds of feet of historic sidewalk paving largely in good repair.
