Modern Vintage in Brookline, MA

Behind its iconic Tudor-style facade, Alden Castle reveals an architecturally stunning event venue.

Discerning engaged couples choose Alden Castle for its Old-World grandeur and vintage romance.



The Vintage Ballroom + Mezzanine is Boston’s preeminent historic ballroom venue for wedding receptions, fund-raising galas, and film and fashion events.
