Looking north from Killian Court, a visitor to the Massachusetts Institute of Technology is treated to one of the most iconic views of academic life in the United States, and certainly one of the most recognizable in Cambridge the Great Dome. Like all great works of architecture, the Great Dome was designed to make a statement and more than a century after its completion, it still does.
The Great Dome towers 150 feet over the Barker Reading Room, both its height and architectural details meant to inspire classical ideals. Like cathedrals and institutions of higher learning throughout the world, the dome is meant to elicit a sense of awe, of reverence. It says to the viewer: this is a rarefied space.
Central location of the MIT Great Dome
The Great Dome’s central location in the heart of MIT’s campus, as well as its towering height, make it one of Cambridge’s most recognizable and accessible attractions. Surrounded by the rich greens of Killian Court, the Dome is a popular spot with both tourists and students and is the backdrop for commencements and countless campus events.
The oldest building on campus, the Great Dome is so strongly associated with Cambridge that it might be said to belong as much to the city as to the institute.
The dome was constructed in 1916, after MIT relocated from Boston‘s Back Bay to Cambridge. To mark the transition, the Institute planned for an imposing new campus design, a design which would make clear the institution’s focus on excellence and its ambitions for the future. The Dome, towering 150 feet at its tallest point, and larger than that of both the United States Capitol and St. Paul’s Cathedral, would become the centerpiece of the new campus.
Perhaps the most remarkable feature of the Great Dome, however, is one which is only visible from its interior. Inside the 100-foot-wide Great Dome is the rotunda, whose diameter and height are both seventy-five feet. The two domes meet at the circular skylight, or oculus, allowing beams of natural light to flood the Barker Reading Room. The oculus itself is twenty-seven feet in diameter, almost precisely the same size as the oculus in the Parthenon in Rome.
Timing a visit to the Great Dome
The Great Dome is striking at any time of day. In early morning, when the sun is low and the light is soft, the limestone seems to glow against the sky. But I chose to photograph the dome in late afternoon because I wanted to see it in the hazy light of the golden hour. The late afternoon sunlight illuminated the distinct architectural details of the dome and highlighted its neoclassical elements, giving the viewer a sense of the building’s grandeur.
The Great Dome is open to the public and is free to visit.
