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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
