The Commander’s Mansion decked the halls for the annual Christmas Celebration on Thursday night.
The line to visit Santa Claus stretched out the door, through the upstairs hallway and into two more rooms. Visitors could also spend time with Mrs. Claus.
Downstairs, ballroom dancers entertained guests, while children could create a craft of their own.
Everyone enjoyed hot chocolate and cookies at Rudolph’s Cafe.
The event is sponsored by Ballroom in Boston, Kataram Studios, the Watertown Police Department and Watertown Savings Bank.
