The downtown construction site may be a jumble of roaring machines and rubble, but the fence surrounding it has certainly become something special.

But a new face was applied Saturday to a wooden wall around the Bedford Square project rising on the former site of the Westport Weston Family YMCA with “Paint the Town,” a volunteer beautification endeavor. Dozens of residents came out to paint full-body portraits and other art works for a street-length mural on the wall surrounding the construction site.

“It’s very spirited and colorful and unique,” said Kiara Shey, 14, of Westport, who painted with her family.

The event was co-sponsored by the Downtown Merchants Association, Westport Arts Center and Westport Weston Chamber of Commerce.

“Westport has always been a community based on the arts and this proves it,” said Matthew Mandell, the chamber president. “Everyone’s coming out and painting themselves and helping to beautify the wall. It’s a great event.”

David Waldman, a principal of the Bedford Square development team, had the idea for some kind of art project on the construction site’s wall. “It’s just a creative way to take a two-year barricade and make it something exhilarating,” he said.

“I love it,” said John Caddiano of Westport. “I’m an artist, so why wouldn’t I?”

“I think it’s really cool,” said Allie Avila, 13, of Westport. “It’s really artsy.”

“Westport doesn’t usually do things like this,” noted Biz Fay, 13, of Westport. “I think it’s awesome.”

Supervising artists helped amateurs trace their figure on the wall in the pose of their choosing, then the organizers provided paints and brushes to help bring their creations to life.

“It’s inspired everybody,” said Helen Klisser During, the arts center’s artistic director. “Everybody’s that’s participated seems to have had a lot of fun.”

She said that once the portraits — or “selfies” — are finished, artists will complete the mural with images of landmarks from around town “so it’s not just a mismatch.”

“It represents a little slice of the town,” she said.

Carine Lauterbach of Westport, whose daughters participated, said, “It’s fun to get everybody involved in decorating, in making it look pretty, and to have fun of course.”

“I think it’s really fun, and it’s creative to get everyone together,” said Ella Hansen, 10, of Westport.

“I saw it in the paper this morning,” said her mother, Lauri Hansen, “and I said, ‘This is what we’re doing today.’ We love art and we love the town.”
