St. Patrick's Cathedral was constructed starting in 1858 to accommodate the growing Archdiocese of New York and to replace St. Patrick's Old Cathedral. Work was halted in the early 1860s during the American Civil War; the cathedral was completed in 1878 and dedicated on May 25, 1879. The archbishop's house and rectory were added in the early 1880s, both by James Renwick Jr., and the spires were added in 1888. A Lady chapel designed by Charles T. Mathews was constructed from 1901 to 1906. The cathedral was consecrated on October 5, 1910, after all its debt had been paid off. Extensive restorations of the cathedral were conducted several times, including in the 1940s, 1970s, and 2010s.
St. Patrick's Cathedral is clad in marble and has several dozen stained glass windows. It measures 101 m long, with a maximum width of 53 m at the transepts. The bronze doors that form the cathedral's main entrance on Fifth Avenue are flanked by towers with spires rising 100 m. The northern tower contains nineteen bells, and the interior has two pipe organs. Inside is a nave flanked by several chapels; two transepts; a chancel and apse; and a crypt. East of the apse are the rectory, Lady chapel, and archbishop's residence facing Madison Avenue.

The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
