St. John's history. A "poetry wall" and several Madonna paintings are also located in the ambulatory, particularly in the southern part of the ambulatory. Extending outward from the ambulatory are seven chapels. These chapels are known as the "Chapels of the Tongues", and all were donated by prominent individuals and families. The chapels were designed by four different architects and firms: Heins & LaFarge designed two of the chapels, while Cram designed a third. The Chapels of the Tongues were devoted to seven of the city's largest immigrant groups when the apse was completed: the southernmost three chapels represent "Latin races" and the northernmost three chapels represent "Germanic races". All of the chapels, except for St. Ansgar's, were donated by individuals or families. Clockwise from north, they are devoted to: St. Ansgar, patron of Denmark; designed by Henry Vaughan, dedicated 1918. St. Ansgar Chapel has its own organ. St. Boniface, apostle of the Germans; designed by Henry Vaughan, dedicated 1916. St. Columba, patron of Ireland and Scotland; designed by Heins & LaFarge, dedicated 1911. St. Savior (Holy Savior), devoted to immigrants from Africa and Asia; designed by Heins & LaFarge, dedicated 1911. St. Savior was the first chapel to be complete, hosting its first services in 1904. It contains a bronze three-paneled altar with gold-leaf decoration, designed by Keith Haring just before his death. St. Martin of Tours, patron of the French; designed by Cram & Ferguson, dedicated 1918. St. Ambrose, patron of Milan; designed by Carrère and Hastings, dedicated 1914. St. James, patron of Spain; designed by Henry Vaughan, dedicated 1916. St. James Chapel is the largest apsidal chapel, with a seating capacity of 25 people, and is frequently utilized for small funerals, weddings, or worship services. The chapel has its own choir and 857-pipe organ. The northwest corner of the apse, adjacent to the St. Ansgar Chapel, includes the octagonal baptistery. The baptistery was donated by three Stuyvesant family siblings in 1924. The space measures in diameter with a ceiling tall. The baptistery's iconography depicts the Stuyvesant family history; icons of New Amsterdam, New York, and Dutch history; and the 12 apostles. The columbarium, established in the 1970s, is in a room directly west of the baptistery. It contains marble vaults, which store the remains of people from all religions. Crossing Between the nave to the west and the apse to the east is the crossing, designed by
