The man who officiated the wedding in front of about 100 guests told The Boston Globe: "Literally as they were saying 'I do' we saw smoke. ... [The groom] didn’t know what to say or what to do — he was angry and emotional."
Luckily, there were no injuries reported in the weekend fire. According to WBZ-TV, the 108-year-old venue didn't have any sprinklers. Officials say the building is being demolished.
WFXT reports dozens of other couples who had planned to get married at the venue later this year are now having to look elsewhere.
"Our wedding is on a Saturday in the middle of July — the busy season. We already booked our honeymoon. We don't know if we can get that money back. We sent out save the dates."
The building's owner told WHDH she's going to do what she can to help couples find other venues. Officials say they believe the fire was an accident. No one is expected to face charges.
