Shirley Eustis House

Across the street from the enormous Shirley-Eustis estate in Roxbury, the “outbuilding,” as it’s referred to, at 42-44 Shirley Street, has come into its own as a 18th-century landmark — prompting an investigation by the city archaeologist into what secrets may be hiding underground.

The ‘outbuilding’ as it’s referred to, at 42-44 Shirley Street, blends into the other residential structures on the street with modern roofing and windows, and a plain beige exterior. However, after speculation based on archival records of the Shirley-Eustis property, an investigation by Harvard scholar Aabid Allibhai revealed the unassuming building may be holding valuable historic secrets.
