The largest building in New England will officially be renamed next month in honor of the late Boston Mayor Thomas Menino, some eight months after the Legislature ordered the change.

The Mass. Convention Center Authority announced on Tuesday that it will hold an event on Sat., July 12, to formally relabel the Boston Convention & Exhibition Center in the Seaport as the Thomas Michael Menino Convention and Exhibition Center.

The new name is meant to honor Menino, the city's mayor from 1993 until 2014 who oversaw the start of the Seaport building boom.

The change was included in an economic development law that Gov. Healey signed in November. State Sen. Nick Collins, the South Boston Democrat who represents the Seaport, said the relatively new neighborhood of Boston "would not be what it is today without the late Mayor Tom Menino."

"That’s why so many of our colleagues in the Legislature joined in supporting the renaming with a near unanimous vote on the economic development bill last session," he said.

The late mayor's widow, Angela Menino, said her entire family is grateful for "this incredible honor. Tommy believed in the potential of every neighborhood in our city, and in the power of development to improve people's lives.

“We thank our legislative leadership for acknowledging his legacy and his vision for how this convention center would lead to the transformation of Boston's Seaport," she added.
