The Oliver Estate

Historians of colonial New England architecture have traditionally viewed eighteenth century Plymouth County as a rural backwater of poor subsistence farmsteads and small vernacular dwelling houses. An analysis of the estate and ironworks constructed by the Oliver family in Middleborough contradicts this notion.

The sophisticated industrial and domestic structures that made up this industrial plantation illustrate the family’s economic prosperity and social position within their community. Developed between 1744 and 1775, the site originally incorporated a vast water powered ironworks and two mansion houses built by Judge Peter Oliver and his son, Peter Oliver Jr. This complex is significant for historical, technological and architectural reasons.

As one of colonial America's first industrial entrepreneurs, Judge Oliver used his influence in the provincial government of Massachusetts to garner royal contracts for his iron works and brought Middleborough’s economy into the international arena. The rolling and slitting mill built by the Judge in 1750 was one of only two similar works in the Province of Massachusetts.

The Olivers used the wealth generated by their ironworks to build two significant gentry mansions during the third quarter of the eighteenth century. These domestic structures exhibit a level of sophistication which set them apart from local and regional building traditions.

During the final, tumultuous years before the American Revolution, Oliver and his family were branded as loyalists and fled to Canada and then eventually to England. The family’s estate in Middleborough was confiscated and auctioned by the newly independent state of Massachusetts and two inventories of the family’s personal possessions and property were made.

Originally incorporating two dwelling houses laid out in a landscaped park, the estate was described by Governor Hutchinson as “one of the loveliest spots in all his majesty’s colony.” As it exists today, the property developed by the Oliver family in the eighteenth century is a mere shadow of its former glory. Oliver Hall, Judge Oliver's residence was burned by the patriot mob in 1778, and no trace of the magnificent mansion or its landscaped park survives. Thankfully, Peter Oliver Jr.’s house did not share the fate of the Hall. This elegant Georgian mansion remains as a symbol of the architectural legacy of the Oliver family.
