Phillips Woolen Mill is a historic mill at 71 Grove Street in Adams, Massachusetts. The date of its oldest portions is difficult to assess: when it was cleary associated with the firm of Blackinton and Phillips in the 1850s, it may have already included portions of an earlier millworks on the site. Some portions of the mill show signs of Greek Revival architecture, which was no longer in fashion in the 1850s. Benjamion F.
