Columbia University tunnels

Columbia University in New York City has an extensive tunnel system underneath its Morningside Heights campus connecting many of its buildings, used by the university as conduits for steam, electricity, telecommunications, and other infrastructure. Throughout their history, the tunnels have also been used for other purposes, mostly centering around transportation. During the first half of the 20th century, they were used by students to avoid aboveground traffic. When the university housed the Manhattan Project, they were allegedly used to move radioactive material between buildings. During the Columbia University protests of 1968, students used the tunnels to facilitate their occupation of buildings on campus. rdf:langString

rdf:langString ...the Columbia tunnel holds a high place in student regard. On its walls may be seen penciled inscriptions of men who long since have risen to importance in the affairs of the nation. Class after class has wandered through its passages, tracing the year numerals on the dust and leaving hieroglyphic commentaries on certain unpopular members of the faculty.

During the Columbia University protests of 1968, students used the tunnels to facilitate their occupation of buildings on campus. Throughout their history, the tunnels have been thoroughly explored by generations of students, and have been the subject of numerous campus legends. Though sections have been cordoned off by the university since the 1960s, either in response to the 1968 protests or rampant campus typewriter theft, many parts can still be legally accessed. Similar tunnels also exist under the affiliated Barnard College.
