Medfield's downtown dates to the mid 1600s, and the first settlement of the town. Over the town's 350-year history, the main four corners have served as the commercial and civic core. In 2005, the town hired Martha Lyon Landscape Architecture and a team of professional planners to create a vision for improvements to the downtown. The project included design workshops for the citizens and merchants of Medfield and the sharing of information about the visioning process through the town's website. The Visioning and Action Plan included recommendations for future land uses, zoning changes, and streetscape improvements, all designed to restore historical elegance, upgrade vibrancy, and encourage greater public use of the downtown.
