Religious architecture Basilica of Saint Martin and Saint Mary of the Assumption Constructed in 1008 on the site of a pre-Romanesque church dedicated to the
Assumption of Mary, the basilica underwent several expansions over the centuries. In 1482, it was enlarged and remodeled in the
Lombard Gothic style, and in the 1500s, it was enriched with works by
Gian Paolo Cavagna. Adjacent to the basilica is the civic tower, a
Lombard Gothic bell tower built around 1008. Standing 60 meters tall, it is the quintessential symbol of the city, visible from kilometers away. Historically, it served military purposes, signaling dangers to neighboring municipalities. On August 30, 2008,
Poste Italiane issued a
postage stamp commemorating the millennium of the bell tower, featuring an image of it.
Sanctuary of the Madonna of Tears The Sanctuary of the Madonna of Tears opened for worship on 19 June 1619, when the image of the
Madonna of Tears was transferred from the
Augustinian monastery, where the miracle occurred, to the main altar, designed by the
Caravaggian architect
Fabio Mangone. The sword and helmet of the
viscount of Lautrec are still preserved beneath the image. The sanctuary houses
frescoes and paintings by Molinari, the
Galliari brothers, Cresseri, Montalti, and
Bernardino Butinone. In the 19th century, the building was further modified, including its facade, interior, and the addition of a
bell tower. Built after the 1529 plague, it honors the saint traditionally invoked against the plague. It has three naves, with the central nave being taller than the lateral ones. The gabled facade includes a
pronaos-like structure with a pitched roof supported by two pillars. The western wall curves symmetrically with the
apse, adorned with a large mosaic depicting
the calling of St. Peter, created in 1997 by Italo Peresson based on a design by
Trento Longaretti. The church overlooks the modern Piazza Paolo VI and is accompanied by parish facilities and a
bell tower.
Church of Saint Zeno The Church of
Saint Zeno, located northeast of the historic center, is named after the ancient church of Saint Zeno in the village of Cusarola, one of the three
villae that formed Treviglio. Housed in a renovated warehouse, the modern structure is surrounded by
olive trees. Light enters through colorful
stained glass windows by Tito Toneguzzo and sons, based on sketches by
Trento Longaretti, depicting biblical scenes. The building, featuring a
portico at the front, was constructed in the 1970s as the surrounding area developed into a new neighborhood. It was consecrated on Sunday, 18 October 1981, by Cardinal
Carlo Maria Martini.

Civil architecture ;Palazzo Pirovano A building of significant artistic value, located in the city's heart opposite the Sanctuary of the Madonna of Tears. Renowned for its striking beauty and historical prestige, it once housed the Galliari brothers. The palace, protected by cultural heritage organizations, features a grand
Baroque-style entrance hall leading to a garden with an elegant fountain, reminiscent of a Roman
domus. Its rooms are adorned with frescoes and intricate ancient decorations. ;Casa Della Piazza Known as the pilgrims' hospice, Casa Della Piazza faces Piazza Manara, situated between the basilica and the municipal palace. Its facade displays coats of arms and traces of ancient openings framed by brickwork. It was named after Simone Della Piazza, who lived there in the 16th century. Upon his death without heirs in 1529, he willed it to serve as a hospice for pilgrims. ;Casa Semenza This house boasts a painted facade and frescoes in its interior rooms. designed to keep workers occupied and curb social issues such as alcoholism. The street is named after Monsignor Ambrogio Portaluppi, who, through the future rural bank, supported public works aligned with
Rerum Novarum. A
cascina called Santissimo is also located at the rear, built in the early 20th century. ;Former monastery of Benedictine nuns The former Monastery of the Benedictine nuns was built around the Church of St. Peter, constructed in 1037. In 1499, it became a convent of the Poor Clares. From the end of the 18th century until the present day, it has housed the Hospital of Santa Maria. ;Municipal Palace The core of the current municipal palace, documented as the
pallatium novum communitatis in 1269, was completed in 1300. Initially featuring a balcony and two stories, it was fully renovated in 1582. ;Walls and moat The walls built during Venetian rule were demolished between the 19th and 20th century as the city expanded, though they shaped the urban layout of the historic center. Only a height difference near the sanctuary remains visible. The
moat skirting the historic center, once fed by the Mulina canal, lies buried beneath the inner ring road.
Other ;Votive shrines Numerous
votive shrines, significant places of worship with deep-rooted traditions, dot the city. Historically, they served as landmarks for identifying zones and streets before formal
toponymy was established. ;Madonna of Milk At the intersection of Via Municipio and Via Sant'Agostino, a votive shrine depicting the Madonna of Milk, painted by Giacomo Manetta, stands. According to local tradition, new mothers visited the shrine to pray for abundant milk for their newborns, giving rise to its name. Since 1987, the original canvas painting has been removed for safekeeping and replaced with a faithful reproduction. ;Piazza Manara Piazza Manara, the city's central square, is dedicated to Milanese patriot
Luciano Manara, who stayed in a building facing the square. It is flanked by the Basilica of Saint Martin and Saint Mary of the Assumption and the municipal palace. To the southwest, it opens onto the larger, elongated Piazza Garibaldi. Named after Manara in the mid-19th century, it was previously called Piazza San Martino and, in medieval times before the basilica's construction, Piazza della Comunità. The L-shaped square connects to four streets leading to the city's historic gates: Via Roma, Via Fratelli Galliari, Via Verga, and Via San Martino. Other adjacent streets include Vicolo Teatro, a closed alley once behind the social theater, and Via Municipio, which runs alongside the municipal palace for half its length. Nearby stands the Gothic house, built around 1300 with smooth, rounded stones from the
Adda River bed, recently restored. ;Sanctuary Square The square is home to one of the three
obelisks erected in the city in memory of the victims of the
plague of 1630. This obelisk was previously located at the end of the Mulina canal on
Felice Cavallotti street. It is also the site of the Filodrammatici Theatre, characterized by its
Art Nouveau style, the
convent of the
Daughters of the Church, and the remaining part of the
Augustinian monastery, dating back to the 11th century. According to Catholic tradition, the miracle of the weeping
Madonna took place in its church on February 28, 1522. The Augustinian monastery no longer houses any religious order, as it was suppressed with the arrival of Napoleonic revolutionaries. The portico connecting to the Sanctuary and the
Ecce Homo church were removed in the early 20th century during the expansion of the sanctuary, which led to the creation of the square itself.

These coins were likely hidden underground to evade the tax increases imposed by the emperor. ;San Maurizio Church Field Among the main archaeological sites is the field surrounding the San Maurizio Church, where numerous archaeological artifacts have been found. ;Other sites Other artifacts have been found in the fields around the city, particularly near the
frazioni of Castel Cerreto and Pezzoli and the
