Why Piazza Mentana matters.
Piazza Mentana is a secluded historic square where Cinque Vie's medieval character meets the buried architecture of imperial Mediolanum, a vanished Augustinian monastery and a Risorgimento memorial inaugurated before Giuseppe Garibaldi.
Set along Via Santa Marta near Via Morigi and just steps from Via San Sisto, the piazza occupies an irregular opening where narrow medieval streets, restrained residential fronts, institutional buildings and the tall central monument interrupt the compressed street grain extending between the Duomo and Sant'Ambrogio. Via Santa Marta and Via Morigi enter through tight approaches as Via San Sisto draws the southern edge toward the Carrobbio, preserving the fine-grained geometry that distinguishes Cinque Vie from Milan's larger nineteenth-century axes. Luigi Belli's monument dominates the open ground through a high stone base and white marble figure, giving an otherwise modest enclosure an emphatic vertical center. The surrounding architecture maintains comparatively restrained heights and varied alignments, leaving the monument visible through several narrow approaches before the piazza fully opens. The result is a compact square where ancient ground, medieval streets and nineteenth-century commemoration remain compressed inside one of Central Milan's oldest urban districts.
What defines Piazza Mentana.
Piazza Mentana is best known for occupying ground within the western sector of imperial Mediolanum where substantial remains connected with Emperor Maximian's palace complex have been discovered beneath the modern city. Maximian established Milan as an imperial residence during the Tetrarchy at the end of the third century, prompting an immense rebuilding of the western quarter between the circus, Via Torino and the decumanus corresponding with Via Santa Maria alla Porta and Via Santa Maria Fulcorina. The resulting palace was not a single structure but an extensive compound of residential apartments, service buildings, courtyards, porticoes and official reception rooms connected with the exercise of imperial government. Its construction altered the inherited Roman street system as the route corresponding with Via Torino gained importance in connecting the imperial residence with the episcopal territory near the present Duomo. Archaeological discoveries have established major components across Via Brisa, Via Borromei, Via Gorani and Via San Sisto, placing Piazza Mentana directly inside this dispersed architectural complex. Massive foundations discovered beneath the piazza form one of its most substantial surviving sectors and have been interpreted in connection with a possible thermal complex. The imperial structures survived in portions into the tenth century, long after Milan ceased functioning as the western imperial residence. A different institution occupied the area from 1345, when the widow Simona da Casale withdrew to her house for religious devotion and attracted a growing community of women around her. The community adopted the Augustinian rule in 1405 and entered the Observant movement during the following decades under Margherita Lambertenghi. Santa Marta subsequently became one of Milan's significant female monasteries, reaching particular prominence under Arcangela Panigarola during the period of French rule and later serving Carlo and Federico Borromeo as a focal point for reform of the city's female religious communities. Suppression in 1799 divided the property among new uses, removing the monastery that had occupied ground above a far older imperial district.
The Monumento ai Caduti di Mentana gave the former Piazza Santa Marta a new political focus through the unresolved struggle over Rome that followed Italian unification. The Battle of Mentana on November 3, 1867 pitted volunteers led by Giuseppe Garibaldi against Papal and French forces during an unsuccessful campaign toward Rome, which remained outside the Kingdom of Italy. A committee formed in Milan in 1873 after plans emerged for a monument to Napoleon III, whose French forces had defended papal authority during the Mentana campaign. A competition followed in 1874, selecting Piedmontese sculptor Luigi Belli for the memorial to the Italian dead. Authorities assigned the monument a site in Piazza Santa Marta in 1876, and Belli developed a composition centered on a 4.5-meter Carrara-marble figure of Italia turrita standing above a six-meter Baveno-granite pedestal. The figure extends a laurel wreath and holds a sword as bronze reliefs on the base depict Monterotondo and Mentana; Belli inserted his own likeness into the wounded soldier of the Monterotondo relief. Felice Cavallotti supplied the inscription on the rear. Inauguration took place on November 3, 1880, exactly thirteen years after the battle, with Garibaldi attending in a carriage amid an immense public gathering. A photograph preserved by Milan's Civico Archivio Fotografico captures the ceremony and Garibaldi's presence as Henry Rochefort addressed the crowd. The monument subsequently supplied Piazza Mentana with its present name, turning a square formed above Roman and monastic remains into a permanent site of Risorgimento commemoration.
How Piazza Mentana fits.
Piazza Mentana works as the anchor for a daytime exploration of Cinque Vie through three nearby sites that move from a sculptor's reuse of an ancient church through the surviving architecture of a medieval aristocratic compound into the Renaissance rebuilding of Milan's foremost Benedictine convent.
Begin at Studio Museo Francesco Messina, housed inside the former church of San Sisto, whose origin reaches a foundation attributed to the Lombard king Desiderius in 720. Baroque reconstruction produced the single-nave church with two chapels and a facade organized through Ionic pilasters, a central portal and triangular pediment. Religious use eventually ceased, and the building suffered severe damage during the Second World War before the Comune undertook restoration. Francesco Messina received the former church for use as his studio during the later twentieth century, bringing a sculptor whose commissions included major public and religious works into a building carrying more than a millennium of Milanese history. Continue to Torre dei Gorani, the principal medieval survivor of a residential compound whose history reaches the eleventh century. The exposed brick tower preserves bifore and trifore across its upper stage and belongs to the small group of surviving domestic towers that once marked the residences of powerful Milanese families. Palazzo Gorani developed around it through later centuries before bombing in 1943 destroyed the palace, leaving the tower, Baroque portal and sections of perimeter masonry isolated within the ruined site. Subsequent redevelopment retained the tower as the historical center of a reopened urban passage, making its survival especially consequential within a district where wartime destruction removed substantial older fabric. Conclude at San Maurizio al Monastero Maggiore, attached to a Benedictine female community established by the eighth or ninth century and reconstructed from 1503 through one of Renaissance Milan's most ambitious religious campaigns. The church divides into public and cloistered halls through a transverse wall, preserving the physical separation required by the monastic community. Ippolita Sforza and Alessandro Bentivoglio became major patrons after their daughter Bianca entered the convent and became abbess Alessandra in 1522. Bernardino Luini and his workshop subsequently covered extensive surfaces with frescoes, joined across the century by artists associated with Boltraffio, Vincenzo Foppa, the Campi and Simone Peterzano. Gian Giacomo Antegnati constructed the nuns' mechanical organ between 1554 and 1557, completing another major artistic component of a complex whose surviving decoration spans much of sixteenth-century Lombard painting. The progression moves from the adaptation of a Lombard foundation for Francesco Messina's sculpture through the medieval survival of the Gorani residence into the architecture, patronage and painting of San Maurizio, developing three distinct mechanisms through which Cinque Vie and its western edge preserve successive artistic worlds around Piazza Mentana.
