Roman Catholic Diocese of Assisi-Nocera Umbra-Gualdo Tadino

Assisi Cathedral (Italian: Cattedrale di Assisi or Cattedrale di San Rufino di Assisi), dedicated to San Rufino (Rufinus of Assisi) is a major church in Assisi, Italy. This stately church in Umbrian Romanesque style was the third church built on the same site to contain the remains of bishop Rufinus of Assisi, martyred in the 3rd century. The construction was started in 1140 to the designs by Giovanni da Gubbio, as attested by the wall inscription visible inside the apse. He may be the same Giovanni who designed the rose-window on the façade of Santa Maria Maggiore in 1163. The cathedral has been important in the history of the Franciscan order. In this church Saint Francis of Assisi (1182), Saint Clare (1193), and many of their original disciples were baptised. It was on hearing Francis preaching in this church in 1209 that Clare became deeply touched by his message and realized her calling. Tommaso da Celano related that once Saint Francis was witnessed praying in this church while, at the same time, he was seen jumping on a chariot of fire in the Porziuncola. In 1228, while he was in Assisi for the canonization of Saint Francis, Pope Gregory IX consecrated the high altar. Pope Innocent IV inaugurated the finished church in 1253. As of 1986 it is a co-cathedral of the Roman Catholic Diocese of Assisi-Nocera Umbra-Gualdo Tadino.

The Basilica of Saint Clare (Basilica di Santa Chiara in Italian) is a church in Assisi, central Italy. It is dedicated to and contains the remains of Saint Clare of Assisi, a follower of Saint Francis of Assisi and founder of the Order of Poor Ladies, known today as the Order of Saint Clare.

The Chiesa Nuova is a church in Assisi, Italy, built in 1615 on the site of the presumed birthplace of St. Francis, the house of Pietro di Bernardone. It was then called Chiesa Nuova because it was the last church to be built in Assisi at that time. It was erected because, during a visit to Assisi in 1613, Antonio de Trejo, the Spanish Vicar General of the Franciscans, was saddened when he saw the original home of St. Francis becoming dilapidated. With the help of the Spanish Embassy in Rome and through a donation of 6,000 ducats by King Philip III of Spain, he was able to buy the house. Pope Paul V authenticated this purchase on 10 July 1615 and blessed the first stone. On 20 September 1615 this foundation stone was then brought, in a solemn procession, from the Cathedral of San Rufino to the building site. The church was built under the supervision of brother Rufino di Cerchiara, who was perhaps also the architect.The church, built in late Renaissance style, features a high dome divided in coffers, with lantern and a drum. Such a caisson ceiling is a feature of Renaissance architecture. The plan is a Greek cross one, with nave and transepts of the same length, inspired by the church of Sant'Eligio degli Orefici in Rome, one of the few churches designed and built by Raphael. The church is decorated with frescoes by Cesare Sermei and Giacomo Giorgetti (17th century). The high altar was set over the room of St. Francis. One can also visit the shop where Francis sold his cloth and the stairwell in which Francis was imprisoned by his father. This is the place where Francis decided to answer the divine call and to renounce worldly goods. The adjoining friary houses a museum and an important Franciscan library with many codices and rare books.

The Church of Santa Maria Maggiore, also known as Sanctuary of the Spoliation, is a church in Assisi, Umbria, central Italy. The current structure dates from the 11th-12th centuries, although it was built on a pre-existing Palaeo-Christian church; the latter had been in turn erected above a Roman edifice, the so-called "Propertius' Domus" or a temple dedicated to Apollo or, according to the tradition, to Janus. The church served as the city's cathedral until 1036, when the title was moved to the current Cathedral, the church of San Rufino. It has an undecorated façade divided vertically by pilasters. The entrance door is surmounted by an ogival arch and a rose window, dated 1163 and signed by one Johannes, identified by some with Giovanni da Gubbio, the architect of the Assisi Cathedral. The bell tower, built in the 14th century, is in Gothic-Romanesque style. The interior has a basilica plan with a nave and two aisles, separated by pillars. The walls house fresco remains and paintings of the 14th-15th centuries, including a Pietà attributed to Tiberio d'Assisi and works by Pace di Bartolo. It is likely that the walls were entirely frescoed originally. There is also a panel of Madonna with Child from Pinturicchio's school. The crypt, belonging to the 10th-century church, is home to Roman architectural elements, such as decorated walls, pavements, capitals from "Propertius' Domus", and a sarcophagus with a sculpted cross, dating from the 9th century. From the annexed garden remains of the ancient city's walls can be seen. The Church holds the relics of the Blessed Carlo Acutis, making it a site of pilgrimage for many of the Catholic faithful.

The Temple of Minerva (Italian: Tempio di Minerva) is an ancient Roman building in Assisi, Umbria, central Italy. It currently houses a church, Santa Maria sopra Minerva, built in 1539 and renovated in Baroque style in the 17th century. The temple was built in the 1st century BC by will of Gnaeus Caesius and Titus Caesius Priscus, who were two of the city's quattuorviri and also financed the construction. The attribution to the goddess Minerva derives from the finding of a female statue, although a dedication stone to Hercules has been found, and the temple was likely dedicated to this male demi-god. In the Middle Ages the temple housed a tribunal with an annexed jail, as testified by one of Giotto's frescoes in the St. Francis Basilica, which portrays the church windows with bars. Of the ancient temple, the façade has been preserved, with six Corinthian columns supporting the architrave and a small pediment. The columns were originally covered by a very strong plaster, which was perhaps colored. The cella was completely demolished during the church's construction, in the 16th century, while a small section of the temple was found in the 20th century near the altar. The temple was visited and described by the German poet Goethe during his travels in Italy, as the first ancient structure in good condition seen during his life (1786).

The interior has a single nave with ogival barrel vaults. The right wall is home to a rectangular chapel with, at the altar, a wooden crucifix executed by Innocenzo da Petralia in 1637. The nave ends with a deep apse with a modern stone altar, a Baroque wooden tabernacle and the choir.

The monastery has supported a hospital for the sick; an agricultural colony; and the Orphanage Ancajani (the name and linked all'Aate Ancajani), run by the Stigmata Sisters. The Benedictine monks of Cassino are still resident.

The Treasure Museum of the Basilica of Saint Francis contains a collection of sacred art that is on display in two halls found on the northern side of the Cloister of Pope Sixtus IV which is part of the Sacro Convento in Assisi, Italy. The entrance is found on the second level of the Renaissance cloister behind the apse of the Basilica of Saint Francis, which houses the remains of St. Francis of Assisi. Since 1986 the museum has also displayed a collection of works donated to the Conventual Franciscan Friars by the Secular Franciscan and American art critic, Frederick Mason Perkins, who died in Assisi in October 1955. The museum is part of the Associazione Musei Ecclesiastici Italiani (AMEI) and the network Museale Ecclesiastica Umbra (MEU).

San Martino Chapel (Italian: Cappella di san Martino) is a chapel in the Lower Basilica of San Francesco in Assisi, Umbria, central Italy. Commissioned and funded by Cardinal Gentile Portino da Montefiore, it features a cycle of frescoes by Simone Martini (1313–1318), portraying the life of Saint Martin of Tours in 4th-century France. The frescoes are neither dated nor signed, but art historians tend to agree in identifying Martini as their author, based on stylistic and historical reasons.

The Sacro Convento is a Franciscan friary in Assisi, Umbria, Italy. The friary is connected as part of three buildings to the upper and lower church of the Basilica of San Francesco d'Assisi, which contains the body of Saint Francis. St. Francis wanted to be buried at this location outside of Assisi's city walls, called Hill of Hell (Collo d'Inferno - here were the gallows where criminals were put to death), because his master Jesus of Nazareth also was killed like a criminal outside of the city of Jerusalem.
