The Chiesa del Santissimo Redentore (English: Church of the Most Holy Redeemer), commonly known as Il Redentore, is a 16th-century Roman Catholic church located in the Giudecca sestiere of the Italian city of Venice. It was designed by the architect Andrea Palladio and built as a votive church to thank God for the deliverance of the city from a major outbreak of the plague. Located on the waterfront of the Canale della Giudecca, it dominates the skyline of the island of Giudecca. It is a member of the Chorus Association of Venetian churches and contains a number of paintings by artists including Tintoretto, Paolo Veronese and Francesco Bassano.
Il Redentore has one of the most prominent sites of any of Palladio's structures, and is considered one of the pinnacles of his career. It is a large, white building with a dome crowned by a statue of the Redeemer. On the façade a central triangular pediment overlies a larger, lower one. This classical feature recalls Palladio's façade for San Francesco della Vigna, where he used an adaptation of a triumphal arch. Palladio is known for applying rigorous geometric proportions to his façades and that of Redentore is no exception. The overall height is four-fifths that of its overall width whilst the width of the central portion is five-sixths of its height. It has been suggested that there are some Turkish influences in the exterior, particularly the two campaniles which resemble minarets.
As a pilgrimage church, the building was expected to have a long nave, which was something of a challenge for Palladio with his commitment to classical architecture. The result is a somewhat eclectic building, the white stucco and gray stone interior combines the nave with a domed crossing in spaces that are clearly articulated yet unified. An uninterrupted Corinthian order makes its way around the entire interior.
