A building with apparatus for observing natural, especially astronomical, phenomena. The first is said to have been the top of the temple of Belus, at Babylon. On the tomb of Ozimandyas, in Egypt, was another, with a golden circle 200 feet in diameter; that at Benares was at least as ancient as these. The first in authentic history was at Alexandria, about 300 B. C., erected by Ptolemy Soter. The first observatory in Europe was erected at Nuremberg, 1472. by Walthers. The two most celebrated of the sixteenth century were the one erected by Landgrave William IV. at Cassel, 1561, and Tycho Brahe's at Uranienburg, 1567. The first attempt in the United States was at the University of North Carolina, 1824; and the first permanent one at Williams College, 1836.
