SPRINGFIELD — This 250th anniversary of the American Revolution — the opening shots of Lexington and Concord rang out in April 1775 — is a major business opportunity for the state’s $23.6 billion-a-year travel and tourism industry.

“We’re going to have, starting in April, a great 250th celebration,” Gov. Maura T. Healey told reporters Tuesday after the first day of the Governor’s Conference on Travel and Tourism. “People have got to understand that we’re the birthplace of America. The whole revolution. It started here. So we have a lot to celebrate. From Springfield to Boston, in every corner, every region of the state.”
