CONCORD — A backyard bash 50 years in the making arrives Sunday when Gov. Chris Sununu and first lady Valerie Sununu host a concert to celebrate the anniversary of the Bridges House.

“Another Tequila Sunrise,” an Eagles tribute band, will perform at this fete, which will have food trucks, refreshments and family activities.

Children are admitted free to the 1-4 p.m. event while adults can buy tickets for $30 per person or $50 for a couple.

The tickets get you into the concert and a tour of the Bridges House and grounds, officials said.

The stately but humble brick home on Concord’s east side was donated in 1969 by the family of former Sen. and Gov. Styles Bridges.

“The Bridges family donated this home to the state of New Hampshire with the goal that it would be protected and preserved, but that it would also be used by governors, state leaders and the public,” explained Valerie Sununu, who chairs Friends of Bridges House, the non-profit board that oversees all efforts to maintain the property.

Chris Sununu said that, along with his wife, past governors and first ladies have donated countless hours to preserving this historical monument.

“My predecessors, in particular former first lady Susan Lynch and Governor John Lynch, have worked tirelessly to restore, renovate and preserve the Bridges House,” said Chris Sununu. “I am honored to invite the public to join me and other first families to celebrate the 50th anniversary of this incredible property.”

The home is currently managed by the governor’s office, in cooperation with a volunteer board of directors that oversees management. The house has enjoyed a revival of sorts following the renovation efforts led by former first lady Lynch. The home had fallen into disrepair in the ’90s, but with private donations, The Bridges House has been resurrected.

Among the major donors that made this celebration possible are Manchester developer Dick Anagnost, AutoFair Automotive Group, Dartmouth-Hitchcock Health, Eversource, Pat Griffin, Seacoast auto dealer Paul Holloway, Susan and John Lynch, Northeast Delta Dental, and former Republican State Chairman and Concord developer Steve Duprey.

A historically and architecturally significant home built in 1835, it is listed on both the New Hampshire and the national registers of historic places.

The Bridges House serves as the setting for many official state functions held by the governor such as conferences with legislators, civic and business leaders, and visiting dignitaries from around the nation and the world.

The public is welcomed to the house for events such as holiday tree lighting, concerts and tours as well as backyard summertime outings.
