Harvard Graduate School of Arts and Sciences

The 1857 Gate (or Class of 1857 Gate) is a triple-arched gate on the Harvard University campus, in Cambridge, Massachusetts, United States. According to Harvard Magazine, "members of the class were killed on both sides of the fight in the Civil War", making the gate "a very touching memorial to the unbroken bonds of friendship that this class had". Students on both sides helped fund the gate. It has a Latin inscription from Horace's Odes.The gate was relocated 40 feet in 1924. It is on axis with the 1876 Gate.

The Harvard Library is the umbrella organization for the Harvard University libraries and their shared services, such as access, preservation, digital infrastructure, digital imaging, and discovery services. The Harvard Library is nearly 400 years old, making it the oldest library system in the United States. Additionally, the Harvard Library is the largest private library system and largest academic library in the world. Its collection holds nearly 20 million volumes, 400 million manuscripts, 10 million photographs, and one million maps.Harvard Library holds the third largest collection in the United States, after the Library of Congress and Boston Public Library. Based on the number of items held, it is the fifth largest library in the United States. Additionally, Harvard is part of the Research Collections and Preservation Consortium (ReCAP) along with Columbia Libraries, Princeton University Library and New York Public Library, and the Ivy Plus Libraries Confederation, making over 90 million books available to the library's users. The library is open to current Harvard affiliates, and some events and spaces are open to the public. The most recognized building in the Harvard system is Widener Library, situated in Harvard Yard.

Harvard Square is a triangular plaza at the intersection of Massachusetts Avenue, Brattle Street, and John F. Kennedy Street, near the center of Cambridge, Massachusetts, United States. The term "Harvard Square" is also used to delineate the business district and Harvard University surrounding that intersection, which is the historic center of Cambridge. Adjacent to Harvard Yard, the historic heart of Harvard University, the Square (as it is sometimes called locally) functions as a commercial center for Harvard students, as well as residents of western Cambridge and the western and northern neighborhoods and inner suburbs of Boston. The Square is served by Harvard station, a major MBTA Red Line subway and bus transportation hub. In an extended sense, the name "Harvard Square" can also refer to the entire neighborhood surrounding this intersection for several blocks in each direction. The nearby Cambridge Common has become a park area with a playground, baseball field, and a number of monuments, several relating to the Revolutionary War.

The Harvard Square Subway Kiosk is a historic kiosk and landmark located in Harvard Square in Cambridge, Massachusetts. It was built in 1928 as the new main headhouse (entrance building) for the previously-opened Harvard Square subway station. After the station closed in 1981 for major renovations, the kiosk was moved slightly and renovated. The Out of Town News newsstand, which opened in 1955, occupied the kiosk from 1984 to 2019. As of 2019, the City of Cambridge (which owns the structure) plans to convert it for public use.

Lumen Eclipse is a public media arts gallery located in Harvard Square, Cambridge, Massachusetts, founded to expand public awareness of local, national, and international artists. The gallery is situated on two mounted displays on the Tourism Information Kiosk, just outside the Harvard Square MBTA stop, screening motion art daily. The gallery may also be viewed on the Lumen Eclipse website.

Massachusetts Hall is the oldest surviving building at Harvard College, the first institution of higher learning in the British colonies in America, and second oldest academic building in the United States after the Wren Building at the College of William & Mary. As such, it possesses great significance not only in the history of American education but also in the story of the developing English Colonies of the 18th century. Massachusetts Hall was designed by Harvard Presidents John Leverett and his successor Benjamin Wadsworth. It was erected between 1718 and 1720 in Harvard Yard. It was originally a dormitory containing 32 chambers and 64 small private studies for the 64 students it was designed to house. During the siege of Boston, 640 American soldiers took quarters in the hall. Much of the interior woodwork and hardware, including brass doorknobs, disappeared at this time. While designed as a residence for students, the building has served many purposes through the years. After Thomas Hollis donated a quadrant and a 24-foot telescope in 1722, for example, the building housed an informal observatory. Currently, the President of the University, Provost, Treasurer, and Vice Presidents have offices that occupy the first two floors and half of the third. Freshmen reside in the fourth floor. Massachusetts Hall, as Harvard's oldest extant dormitory, has housed many influential people. Founding fathers who lived in Massachusetts Hall include John Adams, John Hancock, Samuel Adams, Elbridge Gerry, and James Otis. Members of the Wigglesworth, Weld, Thayer, Eliot, and Lowell families (among others), whose names now grace other dormitories, also lived in Massachusetts Hall. More recent notable residents of Massachusetts Hall include Alan Jay Lerner, Elliot Richardson, John Harbison, and Jeff Schaffer.

Harvard station is a rapid transit and bus transfer station in Cambridge, Massachusetts. Located at Harvard Square, it serves the MBTA's Red Line subway system as well as MBTA buses. Harvard averaged 18,528 entries each weekday in FY2019, making it the third-busiest MBTA station after Downtown Crossing and South Station. Five of the fifteen key MBTA bus routes stop at the station. Harvard station is located directly beneath Harvard Square, a transportation, business, and cultural focal point in Cambridge. The Red Line rail platforms lie underneath Massachusetts Avenue just north of the center of the square. Many connecting surface transit routes are served by the Harvard bus tunnel, which runs on the west side of the station. The primary station entrance leads to a central atrium fare lobby under Harvard Square; there is also a secondary fare lobby for the Red Line toward the north end of the station, with entrances at Church Street and opposite it, near Harvard's Johnston Gate; and an unpaid entrance to the bus tunnel at Brattle Square.

The Porcellian Club is an all-male final club at Harvard University, sometimes called the Porc or the P.C. The year of founding is usually given as 1791, when a group began meeting under the name "the Argonauts", or as 1794, the year of the roast pig dinner at which the club, known first as "the Pig Club" was formally founded. The club's motto, Dum vivimus vivamus (while we live, let us live) is Epicurean. The club emblem is the pig and some members sport golden pigs on watch-chains or neckties bearing pig's-head emblems.The Porcellian is the iconic "hotsy-totsy final club", often bracketed with Yale's Skull and Bones, Princeton's Ivy Club, Penn's Friars, Dartmouth's Sphinx Club, Cambridge's Pitt Club, and Oxford's The Gridiron Club. A history of Harvard calls the Porcellian "the most final of them all."

The Faculty has produced numerous research discoveries and many distinguished alumni and professors.

The Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) is the engineering school within Harvard University's Faculty of Arts and Sciences, offering degrees in engineering and applied sciences to graduate students admitted directly to SEAS, and to undergraduates admitted first to Harvard College. Previously the Lawrence Scientific School and then the Division of Engineering and Applied Sciences, the Paulson School assumed its current structure in 2007. Francis J. Doyle III has been its dean since 2015.SEAS is housed in Harvard's Science and Engineering Complex (SEC) in the Allston neighborhood of Boston, directly across the Charles River from Harvard's main campus in Cambridge and adjacent to the Harvard Business School and Harvard Innovation Labs.In 2019, Harvard was ranked third worldwide for Engineering and Technology by Times Higher Education.

The Tasty Sandwich Shop, often called "The Tasty", was a restaurant that operated from 1916 to 1997 near the intersection of JFK Street and Brattle Street, at the center of Harvard Square, in Cambridge, Massachusetts. It was housed in the Read Block building, on the site of the home of colonial poet Anne Bradstreet. The Tasty closed in 1997, after 81 years in business. Its location was later used by the chain stores Abercrombie & Fitch, then Citizens Bank and, as of 2021, a CVS Pharmacy.

The Johnston Gate is one of the several entrances to Harvard Yard in Cambridge, Massachusetts. Completed in 1889 after a Georgian Revival design by McKim, Mead, and White, it opens onto Peabody Street (often mistaken for Massachusetts Avenue, from which Peabody Street diverges nearby) just north of Harvard Square. Costing some $10,000, it was the gift of Samuel Johnston (Harvard College class of 1855). Each Harvard Commencement Day for several hundred years, the sheriffs of Middlesex and Suffolk Counties have arrived at Harvard Yard on horseback, preparatory to the Middlesex Sheriff's ritual calling of the celebrants to order. It has become traditional for them to enter via the Johnston Gate.
