The Vassar College Observatory is an astronomical observatory of the private Vassar College, located near the eastern edge of the Poughkeepsie, New York college's campus. Finished in 1865, it was the first building on the college's campus, older even than the Main Building, with which it shares the status of National Historic Landmark. The observatory's significance is due to its association with Maria Mitchell, the first widely known woman astronomer in the United States.
Morrison Observatory is an astronomical observatory owned and operated by Central Methodist University located in Fayette, Missouri (USA). It was named after Bernice Morrison who, in 1874, pledged $100,000 to C. W. Pritchett for the construction of the observatory. Half of that amount would go the construction of the telescope and observatory; the other half to a permanent trust fund. The observatory was built soon afterwards in Glasgow, Missouri at Pritchett College and opened in 1875.
The Warner and Swasey Observatory is the astronomical observatory of Case Western Reserve University. Named after Worcester R. Warner and Ambrose Swasey, who built it at the beginning of the 20th century, it was initially located on Taylor Road in East Cleveland, Ohio, USA. The observatory, which at that time housed a 9.5-inch (24 cm) refractor, was donated in 1919 to the Case School of Applied Science. The newer 24-inch (61 cm) Burrell Schmidt telescope was built in 1939.
The meridian circle is an instrument for timing of the passage of stars across the local meridian, an event known as a culmination, while at the same time measuring their angular distance from the nadir. These are special purpose telescopes mounted so as to allow pointing only in the meridian, the great circle through the north point of the horizon, the north celestial pole, the zenith, the south point of the horizon, the south celestial pole, and the nadir. Meridian telescopes rely on the rotation of the sky to bring objects into their field of view and are mounted on a fixed, horizontal, east–west axis.
Melbourne Observatory was founded in 1862 to serve as a scientific research institution for the rapidly growing city of Melbourne, the capital of the colony of Victoria. The observatory was tasked by the Victorian government with maintaining an accurate time reference for the colony through observations of stars using a transit telescope as well as general astronomical research.
The Theodor Jacobsen Observatory is the on-campus observatory of the University of Washington. Built in 1895, it is the second oldest building on campus and was constructed using the remaining Tenino sandstone blocks from Denny Hall, the oldest and first building on campus. The refracting telescope, enclosed within the dome, has a 6-inch Brashear objective lens on a Warner & Swasey equatorial mount. The observatory also includes a transit room on the west side and a 45-seat classroom, which was built later, on the south side.
Shattuck Observatory is an astronomical observatory owned and operated by Dartmouth College in Hanover, New Hampshire, United States.
The University of Illinois Astronomical Observatory, located at 901 S. Mathews Avenue in Urbana, Illinois, on the campus of the University of Illinois Urbana-Champaign, was built in 1896, and was designed by Charles A. Gunn. It has been listed on the National Register of Historic Places since November 6, 1986, and on December 20, 1989, was designated a National Historic Landmark.
The Detroit Observatory is located on the corner of Observatory and Ann streets in Ann Arbor, Michigan. It was built in 1854, and was the first scientific research facility at the University of Michigan and one of the oldest observatories of its type in the nation. It was designated a Michigan State Historic Site in 1958 and placed on the National Register of Historic Places in 1973.
Fuertes Observatory is an astronomical observatory located on the North Campus of Cornell University in Ithaca, New York. The observatory was designed by L.P. Burnham, Cornell Professor of Architecture and completed in fall of 1917. It was originally used by the Civil Engineering Department as an instructional field office for navigation and surveying. Today, the observatory is primarily used for public outreach, welcoming over two thousand visitors per year with open houses on clear Friday nights.
The Quad is an approximately 22-acre (8.9 ha) quadrangle on the campus of the University of Alabama located in Tuscaloosa, Alabama. Home to most of the university's original buildings, this portion of the campus remains the geographic and historic center of the modern campus. Originally designed by noted English-born architect William Nichols, construction of the university campus began in 1828, following the move of the Alabama state capital from Cahaba to Tuscaloosa in 1826. The overall design for this early version of the campus was patterned after Thomas Jefferson's plan for the University of Virginia, with its Lawn and Rotunda. Following the destruction of the campus during the American Civil War, a new Quad emerged in the late 19th and early 20th centuries. Different in form and function from the original design of the early 19th century, the modern Quad continues to fill its role as the heart of the campus. Although completely surrounded by academic and administrative buildings, only five structures are built directly on the Quad: the Little Round House, Tuomey Hall, Oliver-Barnard Hall, Amelia Gayle Gorgas Library, and Denny Chimes. The remainder of the space is occupied by a grove of trees on the west side and a great lawn on the east. A feature on the northwestern side, known as The Mound, is the site of the old Franklin Hall. A popular gathering place, the Quad is home to pep rallies, a bonfire during homecoming, and numerous day-to-day student activities.
The Gorgas–Manly Historic District is a historic district that includes 12 acres (4.9 ha) and eight buildings on the campus of the University of Alabama in Tuscaloosa, Alabama. The buildings represent the university campus as it existed from the establishment of the institution through to the late 19th century. Two buildings included in the district, Gorgas House and the Little Round House, are among only seven structures to have survived the burning of the campus by the Union Army, under the command of Brigadier General John T. Croxton, on April 4, 1865. The other survivors were the President's Mansion and the Old Observatory, plus a few faculty residences.
The University of Alabama Observatory is an astronomical observatory owned and operated by the University of Alabama in Tuscaloosa, Alabama. The new domed observatory was built atop Gallalee Hall, completed in 1949. It replaced the Old Observatory, which had been in use from 1849 until the 1890s. Initially equipped with a 10-inch (0.25 m) refracting telescope, this was the university's primary telescope from 1950 until 2004. The old telescope was removed and then sold to an antique telescope collector to make way for the new instrument. A new 16-inch (0.41 m) Ritchey-Chrétien reflector, manufactured by DFM Engineering, was installed in 2005.
The President's Mansion is a historic Greek Revival style mansion on the campus of the University of Alabama in Tuscaloosa, Alabama. It has served as the official residence of university presidents ever since its completion in 1841. The structure narrowly avoided destruction during the American Civil War, making it one of the oldest surviving buildings on campus today. The mansion was added to the National Register of Historic Places on January 14, 1972, due to its architectural and historical significance.
The Daniel S. Schanck Observatory is an historical astronomical observatory on the Queens Campus of Rutgers University in New Brunswick, New Jersey, United States, and is tied for the seventh oldest observatory in the US alongside the Vassar College Observatory.
