BATH — There’s likely only one place around where marshmallows can be roasted in a snowman’s heart this weekend, and it’s in downtown Bath.

Part of the city’s month-long holiday celebration, “Bright Night” on Friday, Dec. 14, will showcase the luminaries and window displays of the downtown streets, where lights flash on trees and light poles. Carols will be sung, the Salvation Army Brass Band will play, and the city trolley will roll by, creating a Rockwellian portrait of Christmas in New England.

Organized by Main Street Bath, Bright Night takes place from 5-8 p.m. Log onto visitbath.com for more information.

The event’s theme this year, “Fire and Ice,” reflects two sculptures that will be on display. John Stenquist’s wooden snowman has a heart-shaped chest cavity in which people can roast marshmallows at the corner of Front and Elm streets from 5-8 p.m.

Meanwhile, at the corner of Front and Centre streets, Jason Bluck will show his carving skills on an ice sculpture, possibly another snowman, from 5:30 to 6:30 p.m. Onlookers are invited to take selfies with the sculpture once it’s complete.

For obvious reasons, the burning and frozen sculptures won’t be placed near each other.

“We think about these things,” Mari Eosco – interim Main Street Bath Director and City Council chairwoman – said with a laugh during an interview Dec. 6.

New this year to Bright Night is the “Nonprofit Pop-Up with a Purpose” event, which runs at City Hall (55 Front St.) from 5-8 p.m. The concept, Eosco said, is to have people “give the gift of community through donating money in people’s names, or buying them memberships to one of the organizations” in Bath.

Eosco said she was thinking specifically of her mother, Martha Mayo, the kind of person who “has everything,” and for whom it’s difficult to shop.

“She probably doesn’t need any more squirrel knickknacks; she loves squirrels,” Eosco said. “But I would love to give her (a gift related to) something she cares about in the community. … She thought it would be great.”

The Maine Maritime Museum and Chocolate Church Arts Center are two examples of organizations to which one could either donate funds in someone’s name or buy that person a membership.

“It’s an alternative to keep the money locally,” Eosco said.

Along with the nonprofits that will be displaying information at the event’s tables, the city’s Forestry Committee will offer the opportunity to buy a tree for someone, to be available for planting next spring.

Trolley caroling runs Fridays this month from 4-8 p.m., with free tickets available at the trolley stop, outside City Hall, starting at 3:30 p.m. A gingerbread fundraiser for Hillhouse Assisted Living will be held at the trolley stop from 5-7 p.m.
