Question: La Bella portrait is housed in a Palazzo situated next to which river ?

full_context: Document 1: Young Knight in a Landscape: Young Knight in a Landscape, or Portrait of a Knight, is a painting by the Italian Renaissance artist Vittore Carpaccio, now in the Thyssen-Bornemisza Collection in Madrid. Dated 1510, this is the earliest full-length portrait in Western painting—on the assumption that it is a portrait, as seems likely. It is characteristic of Carpaccio that apart from this important innovation, the style of the work seems in other respects to look back to the previous century. From some date until the 20th century the painting had been given the monogram of Albrecht Dürer, and Carpaccio's signature overpainted. The realism and detail of Carpaccio does in fact show Northern influence.

Document 10: Piazza Cordusio: Piazza Cordusio (also informally referred to as Piazzale Cordusio) is a square in central Milan, Italy. The "piazza" takes its name from the "Cors Ducis" (Ducal court) which was found in the square during Longobard times. It is well known for its several turn-of-the-19th-century Neoclassical, eclectic and Art Nouveau buildings, banks and post offices. Even though many of these have now relocated elsewhere, it is still an important commercial square in the city and hosts the "Palazzo delle Assicurazioni Generali" (Palace of the Assicurazioni Generali), the "Palazzo del Credito Italiano" (Palace of the Credito Italiano) and the "Palazzo delle Poste (Palace of the Post Office), former Borsa di Milano" (former Milan Stock Exchange). Piazzale Cordusio hosts the Cordusio metro station and is the starting point of the elegant pedestrian Via Dante which leads to the imposing medieval Castello Sforzesco, or Milan Castle.

Document 13: Buonaccorso Pitti: Buonaccorso Pitti was a prominent Florentine merchant in the late 14th and early 15th centuries. His family was very prestigious and his father very involved in politics. He was a gambler and often made unsafe investments, though he managed to make money from it several times during his life. He bought and sold horses, wine, wool, and clothing among other things. In 1422, he was elected the Standard Bearer of Justice, Florence's highest post. In 1401, while serving as the Florentine ambassador to Bavaria, he, his brothers, and their descendants were ennobled by Rupert, King of Germany, after having saved his life by thwarting a poisoning attempt by the Duke of Milan. His son, Luca, built the Palazzo Pitti in Florence, but never finished it, it was given to him, but he sold it in 1549. Buonaccorso's descendants, the Counts Buonacorsi di Pistoia, moved from Tuscany to Bavaria in the late 19th century. The family emigrated to the U.S. in the early 20th century.
Document 14: La Bella Principessa: La Bella Principessa (English: "The Beautiful Princess"), also known as Portrait of Bianca Sforza, Young Girl in Profile in Renaissance Dress and Portrait of a Young Fiancée, is a portrait in coloured chalks and ink, on vellum, of a young lady in fashionable costume and hairstyle of a Milanese of the 1490s. Sold at auction in 1998 as an early 19th-century German work, some experts have since attributed it to Leonardo da Vinci. In 2010 one of those experts, Martin Kemp, made it the subject of his book "La Bella Principessa: The Story of the New Masterpiece by Leonardo da Vinci". Evidence discovered in 2011 accounting for its provenance has strengthened the case for it being by Leonardo; the sheet appears to have been cut from a Milanese book of which the remainder has long been in Warsaw, which comes from the "milieu" of Ludovico Sforza, Leonardo's employer.
Document 15: Vasari Corridor: The Vasari Corridor (Italian: "Corridoio Vasariano" ) is an elevated enclosed passageway in Florence, central Italy, which connects the Palazzo Vecchio with the Palazzo Pitti. Beginning on the south side of the Palazzo Vecchio, it then joins the Uffizi Gallery and leaves on its south side, crossing the Lungarno dei Archibusieri and then following the north bank of the River Arno until it crosses the river at Ponte Vecchio. At the time of construction, the corridor had to be built around the Torre dei Mannelli, using brackets, because the owners of the tower refused to alter it. The corridor covers up part of the façade of the Church of Santa Felicita. The corridor then snakes its way over rows of houses in the Oltrarno district, becoming narrower, to finally join the Palazzo Pitti. Most of it is closed to visitors.
