St Dominic founded the Order of Preachers so that his friars would go out of their Convents to preach the Gospel throughout the world. This continues being so today. As such, it is difficult to find all the friars together in the Convent since they are always preaching somewhere. But Dominicans also saw to it that their own Conventual churches were specially designed so as to be able to preach to crowds. A good example is this Church of San Esteban. As it usually happens with Conventual Churches of the Order of Preachers, it is especially designed to allow people to see and hear the preacher clearly; so it has only one nave without columns which interrupt sight and obstruct sound. The church is well lit, thanks to its wide windows. Beauty is also very important because we know that it helps us to love God. When one enters the church of San Esteban, one feels absorbed by a beauty that unconsciously leads us to contemplate and love our God, the source of all beauty. Likewise, it is fundamental for Dominican churches to be spacious so that people in large numbers can listen to their preaching and celebrate the Eucharist. All this signify that the church of San Esteban is a massive place. Following the form of a Latin cross, the dimensions of the church are 84 m. long, 14.50 m. wide, 27 m. high at the nave, and 44 m. at the dome. Consequently, it is considered to be the biggest Conventual church - not a parish church - in Europe. From the transept to the base, the nave is of the late Gothic style, with lancet arches, lath pillars and a complicated ribbed-vault. However, the transept, dome and presbytery are of a Renaissance style. The Sponsor of the church was Brother Juan Alvarez de Toledo, son of the second duke of Alba. He started the work in 1524; it was later passed on to Brother Martín de Santiago who was succeeded by Rodrigo Gil de Hotañón. The church was inaugurated with great solemnity in 1610.
