Infinite Corridor

The Infinite Corridor is a 251-meter (823 ft) hallway that runs through the main buildings of the Massachusetts Institute of Technology, specifically parts of the buildings numbered 7, 3, 10, 4, and 8 (from west to east).

Twice a year, in mid-November and in late January, the corridor lines up lengthwise with the position of the Sun, causing sunlight to fill the entire corridor. Named MIThenge, the event is celebrated by students, faculty, and staff.
