Location of Arecibo

Arecibo is the largest city in geographical size on the island. Located in the Northern Coastal Valley region, adjacent to karst zone characterized by the presence of caves and wooded hills. Arecibo is bordering the Atlantic Ocean, north of Utuado and Lares; east of Hatillo; and west of Barceloneta and Florida.

The city is bathed by two rivers, Grande de Arecibo, which runs through the middle of the city and the Tanamá River.

Arecibo is known as La Villa del Capitán Correa, in memory of a battle fought successfully on its shores by Captain Antonio de los Reyes Correa and a handful of Spanish Army soldiers to repel a British invasion by sea lead by Admiral Whelstone in August 5, 1702.

Settled in 1556, Arecibo became the third Spanish settlement. Founded sixty years later, in 1616, when the King of Spain granted that section of land and the Indians on it to Lope Conchillos, under the governorship of Captain Felipe de Beaumont y Navarra. The leader (Indian chief) of these Indians was called Jamaica Aracibo, their yucayeque was named after him and ultimately the town was called by that same name.

The town is also known as La Muy Leal Villa (very loyal).

This instrument, inaugurated in 1963, employs a 1,000-foot (300 meter) spherical reflector consisting of perforated aluminum panels that focus incoming radio waves on movable antenna structures positions about 500 feet (168 meter) above the reflector surface. The antenna can be moved in any direction, making it possible to track a celestial object in different regions of the sky. It collects radio astronomy, terrestrial aeronomy, and planetary radar data for scientists around the world. The telescope was featured in the movies GoldenEye (1995) and Contact (1997).

The National Astronomy and Ionosphere Center developed the observatory and it is operated by Cornell University under a cooperative agreement with the National Science Foundation. Conceived in 1958 by William E. Gordon, a Cornell professor of electrical engineering, the radio observatory has been operated, since its completion in 1963. The Arecibo Observatory owned by Cornell University, is powerful enough to receive signals transmitted by a comparable telescope located 1,000 light-years away.
