Last week, looking out the window of her business, Artemis Yoga owner Liz Padula saw orange cones, yellow caution tape, gravel, and signs saying “no parking” and “sidewalk closed.” The construction zone — in front of the studio and other businesses on the block between Arlington Street and Bigelow Avenue — is part of the Mt. Auburn Street Project. In an effort to keep clients coming in, she decided to make some social media.

Coolidge Square, the heart of East Watertown, will be a construction zone for the next few years, but the area has a pair of new public art pieces to bring a little joy to the area that will endure the chaos of road and sidewalk replacement. https://youtu.be/Yud2pRsSWrU

The project, called “Open for Business,” includes “Transitional,” which incorporates materials you might find in construction — sheets of aluminum and the white and yellow reflective tags used on roads — to create a piece that changes as you look at it from different angles. The piece was created by MASARY Studios, which also produced the Solstice light show at Mount Auburn Cemetery. “Transitional” is on the wall on the side of Coolidge Hardware, on Kimball Road at the corner of Mt.

The City of Watertown invites the community to celebrate the intersection of art and commerce at the opening reception for “Open for Business,” a public art initiative featuring two new site-specific installations in the heart of Coolidge Square. The reception will take place on Wednesday, May 27, 2026, from 6 p.m. to 7:30 p.m. Attendees will have the opportunity to meet the artists, experience the completed works, and explore the diverse local businesses that define the character of the square. Launched during the Mount Auburn Street reconstruction, “Open for Business” was designed to maintain the vibrancy of the district and encourage foot traffic during a period of infrastructure transformation. “These installations serve as a beacon, drawing residents and visitors to rediscover our cherished local establishments,” says Liz Helfer, Public Arts & Culture Planner. “By bringing world-class art to our sidewalks, we are turning a period of construction into an opportunity for discovery.”
