The Iglesia y Convento de Belén is located on the Compestela street #662, occupying the block bordered by the Luz, Picota and Acosta streets.
					
					
The religious complex is composed of 
					a church and a convent. A peculiar vaulted arch, built over 
					the Acosta street, connects the convent to the neighbor 
					buildings. 
When the first members of the Order 
					of Bethlehem arrived in Cuba, they asked the Bishop Diego 
					Evalino de Compostela (1638-1704) for his advice to build 
					their convent. With the contribution of Compostela that had 
					already an idea to create an appropriate place for the 
					recovery of sick people, discharged from the hospitals of 
					the city, the first stone of the church and the hospital was 
					laid. After the death of the bishop the friars used the 
					incomplete building as a center to care for sick people and 
					to distribute food to the poor. The construction of the 
					hospital and the church restarted in 1712 and the church and 
					first cloister that served as a school and infirmary, were 
					completed in 1718. 
In the 18th century, even though there 
					were already good schools like Colegio Seminario de San 
					Carlos, founded by the Bishop Diego Evalino de Compostela as 
					a higher education institute of the Catholic Church in 1689, 
					wealthy families were sending their children to Spain, in 
					order to complete their studies prior to entering the 
					university there. Even so, the children of a significant 
					sector of the aristocracy, merchants and other well-known 
					Creoles and Spaniards, residing in Havana, were receiving 
					their education from the Jesuits, as they were highly 
					credited by their discipline in following the precepts of 
					the Catholic religion. The College of San José, in that the 
					Jesuits held office, was the preferred institution until 
					1767, when the Jesuits were expelled from Spain and the 
					overseas territories.
When the ostracism of the Jesuits 
					was terminated by Pope Pius VII in 1814, they could return 
					to the island. In 1852, Queen Elizabeth II authorized by a 
					royal decree the establishment of a new secondary school in 
					Havana under the aegis of the Jesuits. The Captain General 
					Marquis de la Pezuela assigned the building of the 
					betlemites for the new school in 1854 that had already been 
					confiscated by the Spanish colonial government years ago, in 
					1842. The betlemites had been evicted and since that time 
					the building had been occupied by the second gabo 
					(vice-captain general) and a battalion of the infantry. 
When the soldiers left the building, 
					it was almost in ruins with split walls and occluded doors 
					and windows. The building became the property of the Jesuits 
					that had been able reestablish their society long ago, in 
					order to compensate their properties that had been 
					confiscated by the government a century ago. In 1854 the 
					Jesuits succeeded in making two classrooms in the Bethlehem 
					building ready for the education, and after a formal opening 
					in the same year, the Real Colegio de Belén started with the 
					education.
In 1896, a third level was added to the building on the south wing, destined for the observatory library and a room for weather forecasts and climatologic works. Between 1904 and 1910, on the occasion of the 50th anniversary of the college, the third level was completed in the north wing, and the astronomical tower was erected, in which the Observatory Museum is inaugurated today. The area of the religious complex reached to ten fold of its original area, when the expansion process was completed in 1909.
Beytüllahim or Betlehem is a city 
					in the center of the West Bank in Palestine, known as the 
					birthplace of Jesus.
The Order of Our Lady of Bethlehem 
					was established by Pope Pius II in 1459. The purpose of this 
					order was to defend the island Lemnos in the Aegean Sea that 
					was taken from Mehmed II (Fatih Sultan Mehmet), but when 
					the island was recaptured by the Turks the Order of Our Lady 
					of Bethlehem was suppressed, almost as soon as it was 
					established.
The Order of Bethlehemite Brothers 
					or Bethlehem Brothers (Hermanos de Belén) are a religious 
					institute founded by Pedro de Betancourt in Guatemala in 
					1653. They are also known as the Order of the Brothers of 
					Our Lady of Bethlehem (Orden de los Hermanos de Nuestra 
					Señora de Bethlehem). 
The Jesuits were successful not only 
					in the administration of the college, but also in the 
					meteorological observations. They had established several 
					observatories in different countries until that time, such 
					as in Vatican, Britain, and Belgium. The Colegio Romano, 
					better known as the Vatican Observatory, was their first 
					observatory (1824), the Havana’s Real Observatorio (Royal 
					Observatory) being the fifth. In the Real Observatorio, the 
					climatologic observations were made on the top of the 
					school uninterrupted for 103 years, from 1858 to 1961. The 
					Jesuits, the first official weather forecasters of Cuba, 
					used the observatory particularly to study of hurricanes. 
					Their effort raised the observatory that was the first of 
					its kind in the Caribbean, to one of America 's most important 
					weather stations
The accuracy of the meteorological 
					data based not only on the persevering work of the observers 
					(students and teachers) in Bethlehem Observatory, but also 
					on the high-level technology that they were using. They had 
					imported a new continuous record meteorograph, called Secchi, 
					from France in 1873, that recorded continuously the values 
					of the atmospheric pressure, the direction and speed of 
					the wind, the temperature and humidity of the air and the 
					amount of the rain fall. At that time, the devices of that 
					type were not more than ten in the whole world.
Another value of these meticulous meteorological observations was their use in the work of the Cuban doctors Ambrosio González del Valle and Carlos Juan Finlay on the transmission of cholera and yellow fever.
