In the 18th century Alberto Churriguera erected the second part in imitation of the façade of the church of El Escorial. Capping the balustrade are statues of St. Ambrose, St. Augustine, St. Gregory and St. Jerome. Then the tower on the side of the vestry was erected which, after suffering damage from the Lisbon earthquake (1753), finally fell down in 1841; it was re-erected next to the vestry and is crowned with a statue of the Corazón de Jesús (Sacred Heart).
