Demolition has begun on the last handful of brick buildings on the former Foxborough State Hospital property, making way for a new 42-unit townhome development. The construction project by Douglas A. King Builders constitutes the final phase of the town’s reuse plan for the site once known as the Massachusetts Hospital for Dipsomaniacs and Inebriates. The brick medical complex was constructed in the 1890s and closed in 1975. Redevelopment began in 2005 and includes a shopping plaza and a variety of housing. Because the site is in the National Register of Historic Places, the town’s Historical Commission had to weigh in before the Building Department could authorize the demolition.
