September 1862, raised the Confraternity of the Cord of Saint Joseph was to an archconfraternity. The cord is white, in token of St. Joseph's purity of heart, and has seven knots, denoting his seven joys and sorrows. Members are encouraged to recite daily seven Glorias in honour of St. Joseph. The White Cord of Saint Joseph can be worn around the waist for purity or around the shoulders for obedience. Any priest can bless the girdle, after which when worn for the first time, enrolls one in the Archconfraternity of the Cord of Saint Joseph; the formula "Priest's Blessing of a Cincture" found in the Roman Ritual can be used for this. Confraternities of the Cord of Saint Joseph must be aggregated to the archconfraternity in the Church of St. Roch at Rome in order to enjoy its spiritual favours and indulgences. Architecture The new Church of San Rocco was constructed around 1509. Built as the chapel of the adjacent hospital, it was rebuilt in 1657 to a design by Giovan Antonio de' Rossi. He added a small dome, the sacristy and the new chapel of the "Madonna delle Grazie". Later changes were made introducing the Neo-Classical style to it. A new, Palladio-influenced façade by Giuseppe Valadier was built in 1834, inspired by Andrea Palladio's work on Church of San Giorgio Maggiore, Venice. The coat of arms of Pope Gregory XVI is over the main entrance. Two “Angels holding candles” were added to the façade in 1984. Interior The pulpit was a gift from Pope Benedict XV. The main altarpiece over the main altar is The Apotheosis of St Roch (1674) by Giacinto Brandi. The fresco of St Martin Sharing His Cloak with a Beggar (1885) is by Cesare Mariani. The church has relics of Saint Roch in a silver reliquary. Baldassare Peruzzi's fresco of Our Lady, St Roch and St Anthony the Abbot was extensively restored by Giovanni Battista Gaulli. Peruzzi was an officer of the Confraternity. Other frescoes by Peruzzi were destroyed by floods. There are three chapels on each side: Chapel of Our Lady of Lourdes Chapel of the Nativity (The fresco altarpiece is by Baldassarre Peruzzi.) Chapel of St Anthony of Padua Chapel of the Immaculate Conception Chapel of St Joseph Chapel of St Francis of Paola Giacinto Brandi painted San Rocco intercede per i malati di peste (1673).
