125 High Street

125 High Street is a 30 floor Modern highrise in the Financial District of Boston, Massachusetts. Standing 452 feet (138 m) tall, the highrise is currently the 22nd-tallest building in the city. 125 High Street has approximately 1.8 million square feet (167,000 square meters) of Class A office space. It was designed by Jung Brannen Associates.


The complex consists of four buildings.

  • 125 High St is a 30-story, 950,000 square foot (88,000 square meter) office tower. This building is the tallest component of a development.
  • 145 High St is 21-story, 500,000 square foot (46,000 square meter) office tower. It sometimes also known as the Oliver Street Tower.
  • Along with the two towers it also includes three restored 19th century buildings with six, five and four stories, totaling 41,600 square feet (3,900 square meters).
  • The fire station makes the office towers one of the few highrises with an on-premises municipal fire company.
  • The property also includes a five-level, 850-car underground parking garage.

The exterior is of a unifying granite, with entrances to the building through the High Street Tower and Oliver Street Tower. The two towers are connected via a central 8-story atrium with skylights 150 feet (46 m) above the floor.


NYNEX (now Verizon and formerly Bell Atlantic), one of Massachusetts' largest employers, wished to consolidate into a single headquarters facility. It was formerly the site of the Traveler's Insurance Building. The existing 16-story, 300,000 square foot (28,000 square meter) structure was demolished in 1988 to make room for 125 High Street.
