Palazzo Prosperi-Sacrati

The Addizione Erculea or Erculean Addition is the area of urban expansion created in 1492 by the enlargement of the walled city limits of Ferrara, Italy. It is celebrated as an example of Renaissance urban planning. The walled medieval city of Ferrara was geographically limited from southward expansion by a branch of the delta of the Po river. In 1450, the prior Duke, Borso d'Este (1450) had enlarged slightly the city southward with reclaimed land from the river banks.However, Ercole d'Este had suffered from attacks and sieges from Venice to the north and the Papal states to the South. In 1492, in order to accommodate the burgeoning city and create a more daunting city-fortress to withstand sieges, Ercole d'Este commissioned plans from the architect Biagio Rossetti for an urban expansion north of the city. The walls at this border coincided with the north flank of the Castello Estense. These walls were razed and the moat, present Corso Giovecca, was filled in. Unlike the dense haphazard tracks of the medieval center, the Addizione created a main east-west road (analogous to a Decumanus Maximus) represented now by Corso Porta Po, Biagio Rosetti, and Porta Mare; and north-south street (analogous to a Cardo Maximus) represented by the now Corso Ercole I d'Este parting from the Castello. The Addizione more than doubled the size of the walled town and included areas for cultivation and private parks (now encompassed by the Cemetery of the Certosa and the Jewish cemetery). Among the buildings erected over the next decades and centuries in this sector were the Palazzina di Marfisa d'Este, the church of Santa Chiara, Palazzo Roverella; the Palazzo Prosperi-Sacrati; the church of Teatini; the church of San Carlo, and the 17th century Teatro Comunale.The walls of Ferrara once spanned 13 kilometers, some 9 kilometers still stand, mainly to the north and east of the city. The Porta degli Angeli was an original Northern entrance to the Addizione Erculea.

The Teatro Comunale (Communal Theatre) in Ferrara is an opera house, located in the Italian region of Emilia-Romagna, and built between 1786 and 1797 with seating for 990. Privately owned theatres with limited seating capacity had existed in the city for many years, but the arrival of Cardinal Spinelli, the new papal envoy, in 1786 spurred the construction of a new public theatre under the architects Cosimo Morelli and Antonio Foschini. However, their disagreements led to conflicting design concepts regarding the elliptical shape of the auditorium which were resolved through compromise. The theatre was finally ready for its inaugural presentation of Portogallo's Gli Orazi e i Curiazi on 2 September 1798. The theatre is noted for staging the premiere of an early opera written by Gioacchino Rossini at the age of twenty, Ciro in Babilonia in March 1812. Between 1825 and 1826 some renovation work was required, followed by some more in 1850, creating the theatre as seen today. In 1928 an orchestra pit was added. During the Second World War the theatre suffered badly from Allied bombing and, although it opened occasionally in the immediate post-war years, it closed in 1956, not to re-open until further restoration took place in the early 1960s and then once again between 1987 and 1989. The present-day auditorium has 5 tiers, while the ceiling displays four scenes from the life of Julius Caesar. It now seats 890. Following the Second World War and subsequent renovations, performances were fairly sporadic, but after the creation of “Ferrara Musica” in 1988, more operatic performances have been staged, some of obscure or little-known operas, and other, more popular works alongside other theatres in the Emilia-Romagna region. The conductor Claudio Abbado usually presented one opera every season and the 2007 schedule showed four operas being staged between February and April, along with dance, theatre and other events of various kinds. Between January and April 2008 the four operas performed were Motezuma by Vivaldi, Maria de Buenos Aires by Astor Piazolla, Tosca by Puccini and Lucia di Lammermoor by Donizetti. The theatre's 2013/14 season shows performances of four operas.

The Palazzo Roverella is a Renaissance-style palace located at the corner of Corso della Giovecca #47, at the intersection with Via Boldini, in Ferrara, Italy. The design and construction of the palace (1508) is attributed to Biagio Rossetti, as commissioned by Gaetano Magnanini, secretary of Duke Alfonso I d'Este. It is built at the land utilized to build the urban expansion of the Addizione Erculea. The palace became property of the Roverella family in the 19th century. The varying rhythm of placement of the windows; and the grotteschi-decorated terra-cotta pilasters with geometric marble bases, give the facade an early-Mannerist-style. Above the pilasters are relief busts.The palace should not be confused with a Palazzo Roverella, Rovigo, also attributed to Rossetti, and which now serves as the town painting gallery.
