The traditional Christmas Tree Lighting on the Londonderry Town Common is being moved to the Clocktower at Londonderry Square, 50 Nashua Rd, because of the construction at the Town Common. Christmas at the Clocktower will be on Sunday, December 8nd. Festivities start at 2:00 pm with entertainment and refreshments.  Then at approximately 3:00 pm, a fire truck will bring Santa and Mrs. Claus to greet the children and pose for pictures with the children. The Londonderry Rotary Club works annually with many youth groups, local non-profit organizations and area businesses to put on this event.
