 Although Bishop St. Palais temporarily resided at Saint Johns when he visited Indianapolis, his successor, Bishop Chatard, formally obtained permission from Pope Leo XIII to establish the bishop's residence at Indianapolis.After Chatard's consecration as Bishop of Vincennes on May 12, 1878, in Rome, Italy, he traveled to Indiana and arrived in Indianapolis on August 17, 1878.Within a month after his arrival in the city, Bishop Chatard commissioned noted Indianapolis architect Diedrich A. Bohlen, principal and founder of the architectural firm of D. A. Bohlen and Son, to design an addition to Saint Johns rectory that would service as the bishop's residence and house the diocesan chancery.
