Roman Catholic Archdiocese of Milan

Santa Maria Maggiore, called the basilica vetus (old basilica) or basilica minor (minor basilica), was a church in Milan, established in 313, which served as co-cathedral alongside Santa Tecla until it was torn down after 1386 to make room for the modern cathedral. It served as the winter cathedral, while Santa Tecla was that of the summer.

Milan Cathedral (Italian: Duomo di Milano [ˈdwɔːmo di miˈlaːno]; Lombard: Domm de Milan [ˈdɔm de miˈlãː]), or Metropolitan Cathedral-Basilica of the Nativity of Saint Mary (Italian: Basilica cattedrale metropolitana di Santa Maria Nascente), is the cathedral church of Milan, Lombardy, Italy. Dedicated to the Nativity of St Mary (Santa Maria Nascente), it is the seat of the Archbishop of Milan, currently Archbishop Mario Delpini. The cathedral took nearly six centuries to complete: construction began in 1386, and the final details were completed in 1965. It is the largest church in the Italian Republic—the larger St. Peter's Basilica is in the State of Vatican City, a sovereign state—and possibly the second largest in Europe and the third largest in the world (its size and position remains a matter of debate).

On 12 June 2023, former Italian prime minister Silvio Berlusconi died at the San Raffaele Hospital in Milan, aged 86, due to complications from a severe form of chronic myelomonocytic leukaemia. On the same day, the Italian government announced a state funeral and proclaimed a national day of mourning for 14 June.

Basilica di Santa Tecla was a former, paleo-Christian basilica church in Milan, region of Lombardy, Italy. It was originally established in 350 and demolished in 1458. Remnants of the structure have been excavated underneath the Milan Cathedral. According to a number of historians the construction of the Basilica was ordered by Roman Emperor Constans in 345 under the name Basilica Maior. It was then founded in 350.

The Teatro Regio Ducale (Italian, "Royal Ducal Theatre") was the opera house in Milan from 26 December 1717 until 25 February 1776, when it was burned down following a carnival gala. Many famous composers and their operas are associated with it, including the premieres of Mozart's Mitridate, re di Ponto, Ascanio in Alba, and Lucio Silla. The opera house also saw the premiere of Maria Teresa Agnesi Pinottini's Ciro in Armenia in 1753; one of the earliest successfully received operas by a female composer. The variant form Regio Ducal Teatro is also seen. The atmosphere in opera houses at the time was very sociable and congenial, and the Teatro Regio Ducale was no exception. The English traveller and music writer Charles Burney describes its faro tables for gambling, and gives this description: The theatre here is very large and splendid; it has five rows of boxes on each side, one hundred in each row; and parallel to these runs a broad gallery ... as an avenue to every row of boxes: each box will contain six persons, who sit at the sides, facing each other. Across the gallery of communications is a complete room to every box, with a fireplace in it, and all conveniences for refreshments and cards. In the fourth row is a pharo table, on each side of the house, which is used during the performance of the opera. After the destruction of the Teatro Regio Ducale, which had been a wing of the Palazzo Reale (Royal Palace), two new theatres were commissioned to be built near the site, both designed by Giuseppe Piermarini. The Nuovo Regio Ducal Teatro alla Scala (with variant forms of its name), the present-day La Scala, was inaugurated on 3 August 1778. The Teatro alla Canobbiana, now called the Teatro Lirico, was inaugurated on 21 August 1779.

The Royal Palace of Milan (Italian: Palazzo Reale di Milano) was the seat of government in the Italian city of Milan for many centuries. Today, it serves as a cultural center and it is home to international art exhibitions. It spans through an area of 7,000 square meters and it regularly hosts modern and contemporary art works and famous collections in cooperation with notable museums and cultural institutions from across the world. More than 1,500 masterpieces are on display annually. It was originally designed to include two courtyards but these were later dismantled to make room for the Duomo. The Palazzo is located to the right of the Duomo's facade, opposite to Galleria Vittorio Emanuele II. The facade of the Palazzo creates a recess in Piazza del Duomo which functions as a courtyard, known as the Piazzetta Reale (literally, a "Small Royal Square"). The famous Hall of Caryatids can be found on the main floor of the building, heavily damaged by World War II's air raids. After the war the Palazzo remained abandoned for over two years and its condition further deteriorated. Many of the Palazzo's neoclassical interiors were lost in this period.

San Gottardo in Corte or San Gottardo a Palazzo is a church in Milan, northern Italy. It was built as Ducal Chapel by Azzone Visconti in 1330, and finished in 1336, as indicated by an inscription on the walls. It was originally dedicated to the Blessed Virgin but Azzone, who had gout, later changed the dedication to St. Gotthard of Hildesheim, patron of those with gout. The design was by Francesco Pecorari from Cremona. The octagonal bell tower has the first example of public clock (before, sun-dials were used). The interior was restored in the Neoclassicist era by Giocondo Albertolli. Of the original church, part of the Giottesque Crucifixion, a canvas with St. Charles Borromeo by Giovan Battista Crespi and the tomb of Azzone Visconti remain.

The Province of Milan (Italian: Provincia di Milano) was a province in the Lombardy region, Italy. Its capital was the city of Milan. The area of the former province is highly urbanized, with more than 2,000 inhabitants/km2, the third highest population density among Italian provinces, just below the densities of the provinces of Naples and of Monza e Brianza, the latter of which was created in 2004 from the north-eastern part of the province of Milan. On January 1, 2015 the province was replaced by the Metropolitan City of Milan.

The Metropolitan City of Milan (Italian: città metropolitana di Milano; Milanese: cittaa metropolitana de Milan [tʃiˈtɑː metrupuliˈtana de miˈlãː]) is a metropolitan city in the Lombardy region, Italy. It's the second most populous Metropolitan City in the nation after the Metropolitan City of Rome. Its capital is the city of Milan. It replaced the Province of Milan and includes the city of Milan and other 133 municipalities or communes (comuni). It was first created by the reform of local authorities (Law 142/1990) and then established by the Law 56/2014. It has been operative since 1 January 2015. The Metropolitan City of Milan is headed by the Metropolitan Mayor (Sindaco metropolitano) and by the Metropolitan Council (Consiglio metropolitano). Since June 2016 Giuseppe Sala, as mayor of the capital city, has been the mayor of the Metropolitan City.

Duomo is an interchange station serving Lines 1 and 3 of the Milan Metro. The station is underground and located at Piazza Duomo, the central area of Milan. The Line 1 station was opened on 1 November 1964 as part of the inaugural section of the Metro, between Sesto Marelli and Lotto. In 1990, it became an interchange with Line 3. The Line 3 platform serving trains to San Donato has several problems with moisture as it is at a depth of about 25 meters. Line 1, being older, runs above Line 3. The Line 3 section is divided into two orthogonal tubes, the northern one being above the southern one. Near the station are the Duomo, the Teatro alla Scala, the Royal Palace and the Galleria Vittorio Emanuele II. A corridor of the station is in communication (but the passage is closed) with the archaeological excavations of the pre-Christian basilica located under the Duomo. The mezzanine of the station is connected by tunnels that reach the exits of Piazza Cordusio ("Craft Gallery"), Palazzo Reale ("Galleria del Parvis"), Corso Vittorio Emanuele II and the Rinascente in Piazza Duomo.

The Museo del Novecento ("museum of the twentieth century") is a museum of twentieth-century art in Milan, in Lombardy in northern Italy. It is housed in the Palazzo dell'Arengario, near Piazza del Duomo in the centre of the city. The museum opened in December 2010. It displays about 400 works, most of them Italian, from the twentieth century.

Piazza del Duomo ("Cathedral Square") is the main piazza (city square) of Milan, Italy. It is named after, and dominated by, Milan Cathedral (the Duomo). The piazza marks the center of the city, both in a geographic sense and because of its importance from an artistic, cultural, and social point of view. Rectangular in shape, with an overall area of 17,000 m2 (about 183,000 sq ft), the piazza includes some of the most important buildings of Milan (and Italy in general), as well some of the most prestigious commercial activities, and it is by far the foremost tourist attraction of the city. While the piazza was originally created in the 14th century and has been gradually developing ever since (along with the Duomo, which took about six centuries to complete), its overall plan, in its current form, is largely due to architect Giuseppe Mengoni, and dates to the second half of the 19th century. The monumental buildings that mark its sides, with the main exception of the Duomo itself and the Royal Palace, were introduced by Mengoni's design; the most notable of Mengoni's addition to the piazza is the Galleria Vittorio Emanuele II arcade.
