Treasure Museum of the Basilica of Saint Francis in Assisi

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.

The Basilica of Saint Francis of Assisi (Italian: Basilica di San Francesco d'Assisi; Latin: Basilica Sancti Francisci Assisiensis) is the mother church of the Roman Catholic Order of Friars Minor Conventual in Assisi, a town in the Umbria region in central Italy, where Saint Francis was born and died. It is a Papal minor basilica and one of the most important places of Christian pilgrimage in Italy. With its accompanying friary, Sacro Convento, the basilica is a distinctive landmark to those approaching Assisi. It has been a UNESCO World Heritage Site since 2000. The basilica, which was begun in 1228, is built into the side of a hill and comprises two churches (known as the Upper Church and the Lower Church) and a crypt, where the remains of the saint are interred. The interior of the Upper Church is an important early example of the Gothic style in Italy. The Upper and Lower Churches are decorated with frescoes by numerous late medieval painters from the Roman and Tuscan schools, and include works by Cimabue, Giotto, Simone Martini, Pietro Lorenzetti and possibly Pietro Cavallini. The range and quality of the works give the basilica a unique importance in demonstrating the outstanding development of Italian art of this period, especially if compared with the rest of Christian Europe.

The Abbey of St. Peter in Assisi, Italy, is inhabited by a small community of monks belonging to the Benedictine Cassinese Congregation. They live according to the Rule of St. Benedict, summarized as "Ora et Labora".Cistercian monks, monks Cassinesi came from the nearby monastery of San Pietro in Perugia, at the invitation of Pope Paul V in January 1613. 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 church of Santo Stefano (Saint Stephen) is a medieval church of Assisi, in central Italy.

The Rocca Maggiore is a castle which dominated, for more than eight hundred years, the citadel of Assisi and the valley of Tescio, constituting the most viable fortification for their defense.

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 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 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.

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 Italian Catholic Diocese of Assisi-Nocera Umbra-Gualdo Tadino (Latin: Dioecesis Assisiensis-Nucerina-Tadinensis) in Umbria, has existed since 1986. In that year the historic Diocese of Assisi, known as the birthplace of Francis of Assisi, was combined with the Diocese of Nocera Umbra-Gualdo Tadino. The diocese is a suffragan of the Archdiocese of Perugia-Città della Pieve.
