Levien Gymnasium

Pupin Physics Laboratories , also known as Pupin Hall, is home to the physics and astronomy departments of Columbia University in New York City. The building is located on the south side of 120th Street, just east of Broadway. In 1965, Pupin was named a National Historic Landmark for its association with experiments relating to the splitting of the atom, achieved in connection with the later Manhattan Project. In 2009 the American Physical Society named Pupin Hall a historic site and honored Isidor Isaac Rabi for his work in the field of magnetic resonance.

Rutherfurd Observatory is the astronomical facility maintained by Columbia University named after Lewis Morris Rutherfurd. Initially, Rutherfurd housed its telescopes and equipment in midtown Manhattan and later on the Stuyvesant Estate. When the Morningside campus was built, telescopes were kept in a "transit building" where the Interdisciplinary Science Building now stands. When Pupin Physics Laboratories were completed in 1927, the home of the observatory was moved to the top of the building. Below the Rutherfurd Observatory on the 14th floor was the site of Professor Wallace Eckert's Astronomical Laboratory, in which he constructed the first device to perform general scientific calculations automatically in 1933-34. The observatory formerly included a twelve-inch (30 cm.) refractor telescope built by the Alvan Clark firm in 1916 for the Czarist government of Russia. It was to be installed at a site to observe an upcoming solar eclipse in Russia. With unrestricted U-boat warfare during World War I, shipment was delayed until the war ended. The new Russian government headed by Lenin refused to pay for or accept the telescope, which sat in a crate in a warehouse until 1920, when Columbia bought it. The telescope was for many years used almost entirely for student education. It was sold in 1997 to South Carolina State Museum, which specializes in the upkeep of the old Alvan Clark refractors.In the 1970s, the "Columbia CO Survey" built a 1.2-meter radio telescope that operated out of the Little Dome and was the first to map the sky in this important radio band.Rutherfurd observatory has been in continuous operation since Pupin was constructed, but in 2009 a new "Northwest Corner Building" was erected next to it, six floors higher than the roof of Pupin and blocking a significant portion of its field of view, and putting out a considerable amount of light, interfering with observations in the remaining sky.

Teachers College, Columbia University (TC) is the graduate school of education of Columbia University, a private research university in New York City. Founded in 1887, Teachers College has served as one of the official faculties and the Department of Education of Columbia University since 1898 and is consistently ranked among the top 10 graduate schools of education in the United States (currently 7th as of 2022). It is the oldest and largest graduate school of education in the United States. Although it was founded as an independent institution and retains some independence, it has been associated with Columbia University since shortly after its founding and merger with the university. Teachers College alumni and faculty have held prominent positions in academia, government, music, non-profit, healthcare, and social science research just to name a few. Overall, Teachers College has over 90,000 alumni in more than 30 countries. Notable alumni and former faculty include John Dewey, Art Garfunkel, Dr. Ruth Westheimer (Dr. Ruth), Carl Rogers, Margaret Mead, Bill Campbell, Georgia O'Keeffe, Edward Thorndike, Rollo May, Donna Shalala, Albert Ellis, William Schuman (former president of the Juilliard School), Lee Huan (Premier of the Republic of China), Shirley Chisholm (first black woman elected to the United States Congress), Hafizullah Amin (leader of Afghanistan), Hamden L. Forkner (founder of Future Business Leaders of America), and E. Gordon Gee (has held more university presidencies than any other American including Brown University and Vanderbilt University).

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. 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.

Burke Library of the Union Theological Seminary is located at 3041 Broadway, in the Morningside Heights neighborhood of Manhattan, New York City. Founded in 1838, since 2004 it has been a part of the Columbia University Libraries. Holding over 700,000 items, it is one of the largest theological libraries in North America.Burke Library began with the purchase of the Leander van Ess collection in 1838, described by Cornell University professor Thomas Frederick Crane as "the most valuable library which has ever been brought into the country.": 352  The van Ess collection can be traced back to the library of the Benedictine abbey at Marienmünster, where van Ess was a member. Following the 1801 Treaty of Lunéville, the monastery's library was split among its members in preparation for its dissolution under Napoleon; van Ess' portion would eventually be sold to the Union Theological Seminary. The collection consisted of around 13,000 volumes, especially rich in pre-1500 incunabula; original editions of patristic literature; Roman Catholic theology, liturgies, and canon law; early Greek, Latin, Hebrew, and polyglot editions of the Bible; as well as a significant group of pamphlets written by Martin Luther written during the 1520s.: 353  Early librarians included professors Edward Robinson, Henry Boynton Smith, and Charles Augustus Briggs.: 353–354 The library would continue to grow, reaching a size of 115,000 volumes by 1899, making it the largest American theological seminary library and tenth-largest college library in general at the time.: 352  Notable acquisitions during the time include the McAlpin collection, donated by David Hunter McAlpin;: 355  donations from Ezra Hall Gillett, Samuel Hanson Cox, William Buell Sprague, and John Marsh; as well as a 7,000 volume gift from Edwin Francis Hatfield.: 356  In 1880, New York Governor Edwin D. Morgan donated $100,000 to the library, which went toward the construction of a new building for the library and the establishment of a permanent fund.Due to increasing costs, Burke Library was acquired by the library of Columbia University, which the Union Theological Seminary is affiliated with, in 2004. Its collections were fully integrated into those of the Columbia Libraries, while allowing Union Theological Seminary and Columbia students and faculty full access to either institution's libraries.

The Bloomingdale Insane Asylum (1821–1889) was an American private hospital for the care of the mentally ill, founded by New York Hospital. It was located in the Morningside Heights neighborhood of Manhattan in New York City, where Columbia University is now located. It relocated to White Plains, New York, as the Payne Whitney Psychiatric Clinic, now known as the "NewYork-Presbyterian Westchester Behavioral Health Center."The road leading to the asylum from the thriving city of New York (at the time consisting only of lower Manhattan) was called Bloomingdale Road in the 19th century, and is now called Broadway. The term "Bloomingdale" dates back to the era of Dutch rule in New Amsterdam, and is possibly a reference to "Bloemendael," the name of a small village in the flower-growing region near Haarlem in the Netherlands. Bloomingdale is described as being a small village on the island, in Spafford's Gazetteer, of 1813.
