San Cassiano (English: Church of Saint Cassian) is a 14th-century Roman Catholic church located in the San Polo sestiere of the Italian city of Venice. A church has stood on the site since 726 with the present building dedicated to Saint Cassian of Imola being consecrated in 1376 and re-modelled during the 17th century. It has a plain exterior with several adjacent buildings overlapping it. Its interior however is richly decorated in a Baroque style. The church is located on the Campo San Cassiano, site of the world's first public opera house, west of the Rialto Bridge and is open to visitors Tuesday-Saturday mornings.The church houses three paintings by the Italian artist Tintoretto, including The Crucifixion of Christ painted in 1568 which the art critic John Ruskin described as, "the finest [example of a Crucifixion painting] in Europe". However, the most famous painting associated with the church is paradoxically one which is no longer there. The San Cassiano altarpiece, painted for this church by Antonello da Messina, was the first major example of oil painting in the city. It disappeared from the church in the 17th century and was cut into sections; the remaining known pieces are re-united in Vienna.

The Ca' Pesaro is a Baroque marble palace turned art museum, facing the Grand Canal of Venice, Italy. Today it is one of the 11 museums run by the Fondazione Musei Civici di Venezia system. The building was originally designed by Baldassarre Longhena in the mid-17th century, the construction was completed by Gian Antonio Gaspari in 1710. As at Longhena's Ca' Rezzonico, a double order of colossal columns and colonnettes flanking arch-headed windows, reinterpreting a motif of Jacopo Sansovino, Longhena creates the impression of double loggias extending across the main Grand Canal frontage, above a boldly rusticated basement.

Palazzo Corner della Regina, commonly known as Ca' Corner della Regina, is a Baroque-style palace in the Sestiere Santa Croce of the city of Venice, Italy. In the English language, the title conforms with Palace of the Queen from the "Corner (or Cornaro) Family"; it is so named because Caterina Cornaro, who became Queen of Cyprus by marriage, was born to this family and at this site in 1454. The palace is located on the Grand Canal, near Ca' Pesaro, and between Ca' Favretto and Palazzo Correggio. The opposite structure is Palazzo Contarini Pisani.

Ponte delle Tette is a small bridge on the rio di san Canciano in the parish of San Cassiano, Venice, Italy, in the sestieres of San Polo.

During the Napoleonic occupation, it was deconsecrated and only reconsecrated in 1851. For a time it was used as a prison for political prisoners. It was re-closed in 1984, and is now mainly an archive. The facade retains bits of Gothic architecture decoration.

The Teatro San Cassiano (or Teatro di San Cassiano and other variants) in Venice was the world’s first public opera theatre, inaugurated as such in 1637. The first mention of its construction dates back to 1581. The name with which it is best known comes from the parish in which it was located, San Cassiano (Saint Cassian), in the Santa Croce district (‘sestiere’) not far from the Rialto. The theatre was owned by the Venetian Tron family and was the first ‘public’ opera house in the sense that it was the first to open to a paying audience. Until then, public theatres (i.e., those operating on a commercial basis) had staged only recited theatrical performances (commedie) while opera had remained a private spectacle, reserved for the aristocracy and the courts. The Teatro San Cassiano was, therefore, the first public theatre to stage opera and in so doing opened opera for wider public consumption. In 2019 a project, conceived by the English entrepreneur and musicologist Paul Atkin, was announced to reconstruct in Venice the Teatro San Cassiano of 1637 as faithfully as academic research and traditional craftmanship will allow, complete with period stage machinery and moving stage sets. The project aims to establish the reconstructed Teatro San Cassiano as a world-renowned centre for the research, exploration and staging of historically-informed Baroque opera.

San Polo (Venetian: San Poło) is the smallest and most central of the six sestieri of Venice, northern Italy, covering 86 acres (35 hectares) along the Grand Canal. It is one of the oldest parts of the city, having been settled before the ninth century, when it and San Marco formed part of the Realtine Islands. The sestiere is named for the Church of San Polo. The district has been the site of Venice's main market since 1097, and connected to the eastern bank of the Grande Canal by the Rialto bridge since the thirteenth century. The western part of the quarter is now known for its churches, while the eastern part, sometimes just called the Rialto, is known for its palaces and smaller houses. Attractions in San Polo include the Rialto Bridge, the Church of San Giacomo di Rialto (according to legend the oldest in the city), the Campo San Polo with the Church of San Polo, the House of Goldoni, the Church of Santa Maria Gloriosa dei Frari, the Church of San Rocco and the Scuola Grande di San Rocco.
