the populist Five Stars Movement. The conservatives have governed the region almost uninterruptedly since 1970. The regional council has 48 members from the centre-right coalition, 18 from the Centre-left coalition and 13 from the Five Star Movement. The seat of the regional government is Palazzo Lombardia that, standing at , is the fifth-tallest building in Milan. Cityscape Skyline Two business districts dominate Milan's skyline: Porta Nuova in the north-east (boroughs n° 9 and 2) and CityLife (borough n° 8) in the north-west part of the commune. The tallest buildings include the Unicredit Tower at 231 m (though only 162 m without the spire), and the 209 m Allianz Tower, a 50-story tower. Architecture There are only few remains of the ancient Roman colony, notably the well-preserved Colonne di San Lorenzo. During the second half of the 4th century, Saint Ambrose, as bishop of Milan, had a strong influence on the layout of the city, reshaping the centre (although the cathedral and baptistery built in Roman times are now lost) and building the great basilicas at the city gates: Sant'Ambrogio, San Nazaro in Brolo, San Simpliciano and Sant'Eustorgio, which still stand, refurbished over the centuries, as some of the finest and most important churches in Milan.

The gilt bronze statue of the Virgin Mary, placed in 1774 on the highest pinnacle of the Duomo, soon became one of the most enduring symbols of Milan.

Notable architects involved in the project included the Florentine Filarete, who was commissioned to build the high central entrance tower, and the military specialist Bartolomeo Gadio. The alliance between Francesco Sforza and Florence's Cosimo de' Medici bore to Milan Tuscan models of Renaissance architecture, apparent in the Ospedale Maggiore and Bramante's work in the city, which includes Santa Maria presso San Satiro (a reconstruction of a small 9th-century church), the tribune of Santa Maria delle Grazie and three cloisters for Sant'Ambrogio. The Counter-Reformation in the 16th to 17th centuries was also the period of Spanish domination and was marked by two powerful figures: Saint Charles Borromeo and
