The Commander's Mansion is a historic event venue, originally built for the Commanding Officer of the Watertown Arsenal in 1865 and currently owned by the City of Watertown.  Set just under nine miles from the heart of Boston, our estate is the ideal country-in-the-city setting for your private or social event.  The Mansion sits on seven lush, landscaped acres, including a beautiful grape arbor that makes a stunning backdrop for on site wedding ceremonies.  We host events year-round inside the Mansion itself, and venue rentals from May through October include the use of a 40' by 80' fabric-lined tent over brick pavers with general illumination.
