The Alban Hills (Italian: Colli Albani) are the caldera remains of a quiescent volcanic complex in Italy, located 20 km (12 mi) southeast of Rome and about 24 km (15 mi) north of Anzio. The 950 m (3,120 ft) high Monte Cavo forms a highly visible peak the centre of the caldera, but the highest point is Maschio delle Faete approximately 2 km (1.2 mi) to the east of Cavo and 6 m (20 ft) taller. There are subsidiary calderas along the rim of the Alban Hills that contain the lakes Albano and Nemi. The hills are composed of peperino (lapis albanus), a variety of tuff that is useful for construction and provides a mineral-rich substrate for nearby vineyards.

The Nemi ships were two ships, of different sizes, built under the reign of the Roman emperor Caligula in the 1st century AD on Lake Nemi. Although the purpose of the ships is speculated upon, the larger ship was an elaborate floating palace, which contained quantities of marble, mosaic floors, heating and plumbing, and amenities such as baths. Both ships featured technology thought to have been developed historically later. It has been stated that the emperor was influenced by the lavish lifestyles of the Hellenistic rulers of Syracuse and Ptolemaic Egypt. Recovered from the lake bed in 1929, the ships were destroyed by fire in 1944 during World War II.

Albano Laziale (IPA: [alˈbaːno latˈtsjaːle]; Romanesco: Arbano; Latin: Albanum) is a comune in the Metropolitan City of Rome, on the Alban Hills, in Latium, central Italy. Rome is 25 kilometres (16 mi) distant. It is bounded by other communes of Castel Gandolfo, Rocca di Papa, Ariccia and Ardea. Located in the Castelli Romani area of Lazio. It is sometimes known simply as Albano. Albano is one of the most important municipalities of the Castelli Romani, and a busy commercial centre. It has been also a suburbicarian bishopric since the 5th century, a historic principality of the Savelli family, and from 1699 to 1798 the inalienable possession of the Holy See. It now houses, among other things, the Praetor of the district court of Velletri. The territory of Albano is partially included in the Parco Regionale dei Castelli Romani.

The Algidus Mons, known in English as Mount Algidus, is the eastern rim of the dormant Alban Volcano in the Alban Hills, about 20 kilometres (12 mi) southeast of Rome, Italy. The ridge is traversed by a narrow crevasse called la Cava d'Aglio. It was the site of the ancient Roman Battle of Mount Algidus. The Via Latina, a road that was strategically advantageous in the military history of Rome, leads to Mount Algidus mountain pass. Dionysius of Halicarnassus claimed that a town was founded on the mountain (Dionysius of Halicarnassus, x. 21, xi. 3), but this has not been verified by modern scholarship. Although an extensive fortification lines the Maschio d'Ariano (the hill to the south of the Via Latina), this particular structure was entirely medieval, and therefore did not exist during the time period described by Dionysius. However, some historical topographers have mistakenly included it on maps meant to illustrate Italy during the Western Roman Empire.

Lake Albano (Italian: Lago Albano or Lago di Castel Gandolfo) is a small volcanic crater lake in the Alban Hills of Lazio, at the foot of Monte Cavo, 20 km (12 mi) southeast of Rome. Castel Gandolfo, overlooking the lake, is the site of the Papal Palace of Castel Gandolfo. It hosted the canoeing and rowing events of the 1960 Summer Olympic Games that were held in Rome. The lane marking system developed for these events is commonly referred to as the Albano buoy system.

Parco Chigi (Chigi Park) of Ariccia is a municipal green space of 28 hectares located in the municipality of Ariccia, in the province of Rome, in the area of the Castelli Romani.The first center of the park dates back to the sixteenth century; however, the current configuration is due to a series of interventions carried out by the Chigi family, who owned the park between 1661 and 1988. Today, the entire area is a property of the Municipality of Ariccia. Parco Chigi is annexed to the historic Palazzo Chigi of Ariccia. In regards to the complex of the palace and the park, some well-known architects contributed, such as Gian Lorenzo Bernini and Carlo Fontana.The park is particularly important within the regional park of the Castelli Romani: in fact, it is one of the few green areas of the Colli Albani in which there has been no penetration of chestnut trees, but the oldest plant species have survived, mostly oaks. The park has a rich history dating back to ancient times. The wooded area that now makes up the park was known as nemus Aricinum during the Roman era, and was dedicated to the goddess Diana. After the advent of Christianity, the sacred nature of the forest was lost, and it eventually became a hunting reserve during the Renaissance owned by the Savelli family.In the 17th century, the Chigi family, a prominent Roman noble family, purchased the town of Ariccia and the surrounding area, including the park. They transformed the park into an elegant Baroque garden, featuring statues, fountains, and other ornate features. Other notable features of the park include the Uccelliera, an aviary built in the 17th century, and the Vignola, a small building originally used as a vineyard. The park also contains a neviera, a structure used for storing snow during the summer months.

The Temple of Diana Nemorensis was an ancient Roman sanctuary erected around 300 BC and dedicated to the goddess Diana. The temple was situated on the northern shore of Lake Nemi, beneath the cliffs of the modern city of Nemi (Latin nemus Aricinum). It was a pilgrimage site on the Italian peninsula. The temple complex covered an area of 45,000 square meters.Historical evidence suggests that worship of Diana at Nemi flourished from at least the 6th century BCE The temple was abandoned at some point in the late Roman Empire period. If still in use by the 4th-century, it would have been closed during the persecution of pagans in the late Roman Empire. Portions of its marbles and decorations were removed. The area of the temple was gradually covered by forest and generally left undisturbed for centuries. Amateur archaeological excavations of the site began in the 1600s.

The Palazzo Chigi of Ariccia was the ducal palace of the Chigi family located in the center of the town of Ariccia, near Rome, Italy. Originally a 15th-century palace of the Savelli family stood at the site, it was rebuilt during 1664 to 1672, in a Baroque style by the Chigi Family. The work was a collaboration between Gian Lorenzo Bernini and his pupil Carlo Fontana. The sober exterior does not reflect the highly decorated interiors. The palace and Parco Chigi were ceded to the Commune in 1988 by the prince Agostino Chigi Albani della Rovere, and now served as a host of exhibitions and events. It hosts the Museo del Barocco Romano encompassed by some of the remaining Chigi family collections. These include the following paintings: Four Seasons by Mario de’ Fiori in collaboration with Carlo Maratti, Bernardino Mei, Giacinto Brandi, Giovanni Maria Morandi, and Filippo Lauri Allegory of the Senses by Pier Francesco Mola Preparatory sketches (cartoons) for mosaics of the cupola of St Peter's Basilica by Cavalier d’Arpino I “feudi Chigi con cani levrieri by Michelangelo Pace also called “il Campidoglio” Finti arazzi commissioned by Cardinal Ottoboni from Domenico Paradisi, Michelangelo Ricciolini and Francesco Borgognone for the Palazzo della Cancelleria Finti arazzi con giochi di putti by Giovanni Battista Magni “il Modanino”; Landscapes by Jos de Momper, Tempestino, and Egidio de Monte Pindar and Pan by Salvator Rosa Blessed Giovanni Chigi in penitence by Giovanni Battista Gaulli called "Il Baciccio" Marine landscape with St Augustine by Jos de Momper and Alessandro Mattia da Farnese.

Santa Maria Assunta is a Roman Catholic parish church designed in 1661–1665 by Gianlorenzo Bernini; and located in the center of the town of Ariccia, Italy, where it stands across a piazza from the Palazzo Chigi Ariccia, once belonging to the family of Pope Alexander VII, Bernini's patrons in the construction of this church.

Palazzo Pamphilj (or del Collegio Nazareno) is a historical palace in the city of Albano Laziale, in the province of Rome, in the Roman Castles area. The palace was built between 1708 and 1717 by Cardinal Benedetto Pamphilj to replace some country houses dating back to the second half of the 17th century located at the top of the trident of Albano, a new urban expansion of the city conceived in the mid-17th century by Cardinal Fabrizio Savelli, commendatory abbot of the church of San Paolo. The palace became the property of the Piarist fathers of Rome's Nazarene College in 1764. It was used as a summer residence for the college's students until 1944, when it was requisitioned for use as a shelter for 52 war-displaced families. It is currently a private property and is in total disrepair and neglect, despite being cited as an illustrative example of a patrician building in the Alban Hills and an 18th-century reconstruction site in a detailed study by Marco Silvestri and Enzo D'Ambrosio for the Accademia degli Incolti in 1988.

The sanctuary of Maria Santissima della Rotonda ('a Ritonna in Albano dialect), formerly known as Santa Maria Maggiore, is an important Marian sanctuary in Lazio, located in the city of Albano Laziale, in the province of Rome, in the Roman Castles area. The sanctuary occupies an ancient round building of Roman construction dating back to the 1st century, traceable to Domitian's villa at Castel Gandolfo, which was formerly a nymphaeum or, according to other hypotheses, a temple. The building was converted to Christian use at the time of Constantine the Great or in the period between the 9th and 11th centuries.Probably run in the first centuries of its existence by religious of the Byzantine rite, it was managed by Augustinian nuns from the 14th century until 1444 and was later assigned to the Girolaminian religious of the basilica of Saints Boniface and Alexius on the Aventine Hill in Rome, who held it until 1663, when the sanctuary was purchased by the suburbicarian diocese of Albano for the purpose of installing the bishop's seminary there. Between 1708 and 1799, the direction of the seminary and the sanctuary passed to the Piarist Fathers. Since then, the sanctuary has been diocesan property and is attached to the parish of the cathedral basilica of San Pancrazio. Today it is listed among the protected architectural monuments of Lazio.

Lake Nemi (Italian: Lago di Nemi, Latin: Nemorensis Lacus, also called Diana's Mirror, Latin: Speculum Dianae) is a small circular volcanic lake in the Alban Hills 30 km (19 mi) south of Rome in the Lazio region of Italy. It takes its name from Nemi, the largest town in the area, that overlooks it from a height. It was formed in an ancient volcanic crater created at least 36,000 years ago.The lake is famous for its great sunken Roman ships built under Caligula.
