Metairie Cemetery is off I-10 at 5100 Pontchartrain Blvd. at the top of Canal St. The largest cemetery in New Orleans, Metairie is a showplace of tomb architecture. Established in 1873 on the site of an antebellum racetrack, it contains fine military memorials; the tomb of Gov. William C. Claiborne, first American governor of Louisiana; the tomb of New Orleans' first African-American mayor, Ernest “Dutch” Morial; and graves of many leading families. Among the elaborate tombs is one built for Josie Arlington, the leading madam of Storyville.
