Il Redentore was built as a votive church in thanksgiving for deliverance from a major outbreak of the plague that decimated Venice between 1575 and 1576, in which some 46,000 people (25–30% of the population) died. The Senate of the Republic of Venice commissioned the architect Andrea Palladio to design the votive church. Though the Senate wished the Church to be square plan, Palladio designed a single nave church with three chapels on either side. Its prominent position on the Canale della Giudecca gave Palladio the opportunity to design a facade inspired by the Pantheon of Rome and enhanced by being placed on a wide plinth. 15 steps were required to reach the church's entrance, a direct reference to the Temple of Jerusalem and complicit with Palladio's own requirement that "the ascent (of the faithful) will be gradual, so that the climbing will bring more devotion".
