The 22-story building houses the world headquarters of Liberty Mutual Insurance Group, standing 290 feet (88 m) tall. The tower cost more than $300 million, and is built in the shape of a triangle, similar to the Flatiron Building. The building's outer appearance is traditional, but the interior is finished with modern architectural touches.

This includes the former American headquarters of Salada Tea which was built in the early 1917.
