Deval Patrick are scheduled at attend a groundbreaking Tuesday for a Boston Tea Party museum. An earlier museum at the site in Fort Point Channel burned in 2001 after being struck by lightning. Griffin’s Wharf, the original site of the December 1773 tea party when colonists dumped tea into the harbor to protest British taxes, was nearby. The mayor’s office says the city and state have approved a $3 million grants for the Boston Tea Party Ships and Museum and the state convention center authority has pledged $18 million. The museum will feature replicas of the three British ships involved in the tea party.
