Dumbarton at Dusk: Happy 91st Birthday!

See Dumbarton House in a whole new light by joining us for after-hours museum tours and birthday fun!

Dumbarton House opened to the public 91 years ago, making us the oldest museum in Georgetown. Come in shorts or in duds from your favorite decade of our long history! Celebrate our historic achievement by partying with us: enjoy live music, light refreshments, birthday cake, lawn games, and visit our newly updated period rooms.

This is a night you won’t want to miss! Light refreshments, a cash bar, and self-guided museum tours will also be available. Support programs like this with a suggested $5 donation.
