Malakoff Tower is a tower located in Recife Antigo, Recife. This monument was built between 1835 and 1855 to be used as an observatory and as the main entrance and gateway for Arsenal da Marinha (Navy Arsenals) square. It has been registered as a Historical Patrimony and was named after a similar monument on the Crimean peninsula, used as a defense center for Sevastopol on the Crimean war. When the arsenals of the Navy were dismantled with the beginning of the Brazilian Republic, the tower was transferred to the heritage of Recife port and then abandoned and endangered. The city population, in association with cultural institutions leadership, mobilized against the demolition, using as an example the real strength of Malakoff on the Crimean war.
The tower was renovated in 1999, keeping the old features of the Tunisian-style monument. Today, it is a cultural area and astronomical observatory:
The United States Naval Observatory (USNO) is one of the oldest scientific agencies in the United States, with a primary mission to produce positioning, navigation and timing for the United States Navy and the United States Department of Defense.
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant or Stonehenge.
Recife is the fourth-largest urban area in Brazil with 4,054,866 inhabitants, the largest urban area of the North/Northeast Regions, and the capital and largest city of the state of Pernambuco in the northeast corner of South America. The population of the city proper was 1,653,461 in 2020. The first slave port in the Americas, Recife was founded in 1537, during the early Portuguese colonization of Brazil, as the main harbor of the Captaincy of Pernambuco, known for its large scale production of sugar cane. It was the former capital Mauritsstad of the 17th century colony of New Holland of Dutch Brazil, established by the Dutch West India Company. The city is located at the confluence of the Beberibe and Capibaribe rivers before they flow into the South Atlantic Ocean. It is a major port on the Atlantic. Its name is an allusion to the stone reefs that are present by the city's shores. The many rivers, small islands and over 50 bridges found in Recife city centre characterise its geography and led to the city being called the "Brazilian Venice". As of 2010, it is the capital city with the highest HDI in Northeast Brazil and second highest HDI in the entire North and Northeast Brazil.

The Mauna Kea Observatories (MKO) are a number of independent astronomical research facilities and large telescope observatories that are located at the summit of Mauna Kea on the Big Island of Hawaiʻi, United States. The facilities are located in a 525-acre (212 ha) special land use zone known as the "Astronomy Precinct", which is located within the 11,228-acre (4,544 ha) Mauna Kea Science Reserve. The Astronomy Precinct was established in 1967 and is located on land protected by the Historical Preservation Act for its significance to Hawaiian culture. The presence and continued construction of telescopes is highly controversial due to Mauna Kea's centrality in native Hawaiian religion and culture, as well as for a variety of environmental reasons.
Steward Observatory is the research arm of the Department of Astronomy at the University of Arizona (UArizona). Its offices are located on the UArizona campus in Tucson, Arizona (US).
