Shell sign shines again

One of Cambridge’s most recognizable landmarks is shining brightly again.

The 93-year-old Shell sign overlooking Memorial Drive atop the Magazine Street Shell station was back in full operation Oct. 27, following months of coordination between the Cambridge Historical Commission, the property’s corporate lessee and a specialized sign contractor.

Eric Hill, the commission’s survey director, said the commission first began receiving complaints about the sign’s deteriorating illumination in December 2025. It was not initially clear who was responsible for maintaining the sign, but the commission eventually connected with SEI Fuels, a subsidiary of 7-Eleven that holds a long-term lease on the property. Company representative Norman Manchester then coordinated with Metro Sign’s Paul DeSantis, who had worked on the sign during a major restoration in 2011 while working for another company.

DeSantis had to inspect the aging electrical system, identify faulty components and obtain specialized replacement parts, some of which required custom manufacturing. Throughout the months-long process, Manchester kept Hill informed of the repairs while the commission continued fielding complaints from residents concerned about the landmark’s condition. “We were getting a lot of emails and calls from members of the public that would drive by and say, ‘Oh my God, the sign is in terrible shape,’” Hill said. “It was just kind of a patchy and flashing sign that wasn’t really showing what it was.”

Built in 1933, the landmark is an example of a type of illuminated advertising known as a “spectacular,” which dotted major thoroughfares in Boston, Cambridge and many other American cities during the early decades of the automobile. Spectaculars used neon lettering and flashing incandescent bulbs to attract passing motorists, often using programmed sequences of lights to create the illusion of movement. “You had a lot of these large rooftop kind of flashing neon signs,” Hill said. “You’d be able to see (them) from across the river.”

The Shell sign was originally installed atop a gas station and office building at 1 University Road in Boston, now home to Boston University Academy, near the BU Bridge. That area was once known as Automobile Row.

Gas stations in the early decades of the automobile were often more architecturally elaborate than their modern counterparts, with oil companies developing distinctive designs to attract customers and distinguish themselves from competitors, Hill said. Some Beacon Oil stations, for example, featured gold domes modeled after the Massachusetts State House, a nod to the company’s namesake, Beacon Hill. Shell’s original Boston station similarly featured decorative seashell motifs incorporated into the building’s architecture, which remain visible on the Boston University Academy facade today.

In 1948, the sign was moved across the Charles River to the Magazine Street Shell station. By the early 2000s, however, decades of exposure to New England weather had taken their toll. The sign’s deteriorating electrical system left portions of its lettering dark, at one point illuminating only the letters “HELL.” It was switched off entirely around 2005 and remained dark for approximately six years.

The Cambridge Historical Commission had twice unsuccessfully sought landmark status for the sign, with opposition stemming from concerns about the British multinational oil company’s corporate practices, though it was listed on the National Register of Historic Places in 1994. In 2009, while the sign was still dark and with little expectation that it would ever shine again, the City Council finally designated it a Cambridge landmark.

That designation helped pave the way for the 2011 restoration, when the deteriorated original sign was dismantled and replaced with a replica based on its original drawings. As part of the project, which cost more than $200,000, the original neon lettering was exchanged for LED lighting while preserving the sign’s historic appearance and flashing sequence, according to a Boston Globe report at the time.

Hill said the sign has long since transcended its original purpose as a corporate advertisement, becoming a familiar part of Cambridge’s landscape, much like the Citgo sign overlooking Kenmore Square, which is Greater Boston’s only other surviving spectacular sign. “It’s just become a landmark … one of those iconic locations in the city that people remember from their past,” Hill said.

The sign’s landmark designation protects it from unauthorized alterations or removal and establishes standards for preserving its historic appearance. Hill said SEI Fuels is responsible for maintaining the historic sign under its long-term lease. The restoration was privately funded and came at no cost to the city.

Cambridge’s current sign ordinance would prohibit the construction of a new spectacular like the Shell sign, Hill said, making preservation of surviving examples all the more important. “Once they’re gone, they’re probably gone for good,” Hill said.
