Angelo Secchi was an Italian Catholic priest and astronomer from the Italian region of Emilia. He was director of the observatory at the Pontifical Gregorian University for 28 years.

The properties of the Holy See are regulated by the 1929 Lateran Treaty signed with the Kingdom of Italy. Although part of Italian territory, some of them enjoy extraterritoriality similar to those of foreign embassies, including tax exemptions. Nonetheless, those visiting these properties are generally required to follow the immigration rules of Italy. For example, American seminarians at the Pontifical North American College need an Italian visa, despite residing, and studying, in extraterritorial property of the Holy See.

The Roman College was a school established by St. Ignatius of Loyola in 1551, just 11 years after he founded the Society of Jesus (Jesuits). It quickly grew to include classes from elementary school through university level and moved to several successive locations to accommodate its burgeoning student population. With the patronage of Pope Gregory XIII, the final seat of the Roman College was built in 1584 near the center of Rome's most historic Pigna district, on what today is called Piazza del Collegio Romano, adding the church of St. Ignatius in 1626, and a renowned observatory in 1787. The college remained at this location for 286 years until the revolutionary Capture of Rome in 1870.
The Vatican Railway was opened in 1934 to serve Vatican City and its only station, Vatican City. The main rail tracks are standard gauge and 300 metres (980 ft) long, with two freight sidings, making it the shortest national railway system in the world. Access to the Italian rail network is over a viaduct to Roma San Pietro railway station, and is guaranteed by the Lateran Treaty dating from 1929. The tracks and station were constructed during the reign of Pope Pius XI, shortly after the treaty.
Francesco Denza was an Italian meteorologist and astronomer.
William R. Stoeger SJ was an American astronomer and theologian.
The relationship between science and the Catholic Church has been both collaborative and contentious throughout history. Historically, the Catholic Church has served as a major patron of the sciences, playing an influential role in the establishment and funding of educational institutions, universities, and hospitals. Many members of the clergy have actively contributed to scientific research. Some historians of science, such as Pierre Duhem, attribute the origins of modern science to medieval Catholic scholars like John Buridan, Nicole Oresme, and Roger Bacon. However, the relationship has not been without conflict. Critics, including proponents of the conflict thesis, point to historical and contemporary tensions between the Church and science, such as the trial of Galileo, as examples of where the Church has opposed scientific findings that challenged its teachings. The Catholic Church, for its part, maintains that science and faith are complementary, as expressed in the Catechism of the Catholic Church, which addresses this relationship.
The Papal Palace of Castel Gandolfo, or the Apostolic Palace of Castel Gandolfo from its Italian name Palazzo Apostolico di Castel Gandolfo, is a 135-acre (54.6-ha) complex of buildings in a garden setting in the city of Castel Gandolfo, Italy, including the principal 17th-century villa, an observatory and a farmhouse with 75 acres (30.4 ha) of farmland. The main structure, the Papal Palace, has been a museum since October 2016. It served for centuries as a summer residence and vacation retreat for the pope, the leader of the Catholic Church, and is afforded extraterritorial status as one of the properties of the Holy See. It overlooks Lake Albano.
The Gregorian Tower or Tower of the Winds is a square tower and early modern observatory located above the Gallery of Maps, which connects the Villa Belvedere with the Apostolic Palace in Vatican City. The tower was built between 1578 and 1580 to a design by the Bolognese architect Ottaviano Mascherino mainly to promote the study of astronomy for the Gregorian Calendar Reform which was commissioned by Pope Gregory XIII and promulgated in 1582. It was then also known as the Tower of Winds. The tower was also called "Specola Astronomica Vaticana", a reference to the Vatican Observatory. Four stages of progressive development have occurred since it was first established. The tower was an edifice of great value for astronomical observations made using a sundial as they provided essential confirmation of the need to reform the Julian calendar.
The term Specola in Italian means observatory, a location used for observing terrestrial or celestial events. A number of palaces, institutes, museums and observatories in Italy carry the name, because at one time or another they housed an observatory. Among these:
Giuseppe Calandrelli was an Italian priest, astronomer and mathematician. He founded the first astronomical observatory in the Collegio Romano in 1787. An uncle of the astronomer Ignazio Calandrelli, he was among the first to observe the parallax of stars, estimate the masses of comets, the potential size of their atmosphere, and to examine the use of barometers to mathematically estimate altitudes.
Ileana Chinnici is an Italian historian of astronomy, book author, and biographer, whose biography of Angelo Secchi won the 2021 Osterbrock Book Prize of the American Astronomical Society.
The Pontifical Villas of Castel Gandolfo are buildings erected in an area of about 55 hectares located in the Roman Castles, in the Metropolitan City of Rome Capital, included among the extraterritorial areas of the Holy See in Italy.
