The streetcar barn is a block off the avenue in Carrollton, on Willow Street, and the landmark Camellia Grill diner is near the corner of St. Charles and Carrollton Avenues. The neoclassical Carrollton Courthouse building is on Carrollton Avenue near the Mississippi; as of 2011 it houses Audubon Charter Middle School. The neighborhood and Avenue are pronounced "kaa-rull-ton" or "kaa-ril-tin" by residents and other uptowners, but many people from the downtown parts of New Orleans (especially those born in the mid-20th century and earlier) pronounce the names as "Karl-ton". Tulane University and Loyola University New Orleans are just a few blocks below Carrollton, and many students, faculty, and staff live in the area and patronize the businesses there. In addition to Carrollton Avenue and Saint Charles Avenue, the neighborhood still retains two "neighborhood main streets" of mixed residential and commercial use. Lower Carrollton centers on Maple Street, with many restaurants, coffee houses, bars, and upscale shops. Upper Carrollton has Oak Street, formerly hosting somewhat larger businesses (such as Woolworth); current businesses there range from restaurants and a hardware store to the best known of the neighborhood's live music venues, the Maple Leaf Bar. In the northwest section of Carrollton on Claiborne Avenue is Palmer Park, which hosts some moderate sized live music festivals each year. The park has a monument to the Carrolltonians who died in World War I. After Hurricane Katrina, Palmer Park hosted the monthly Mid-City art market, displaced from the more severely damaged Mid-City neighborhood. The historically predominantly African-American part of Carrollton along the riverfront has been known since the mid-20th century as "Black Pearl." Mahalia Jackson, the "Queen of Gospel music", was from the Black Pearl section of Carrollton. This part of Carrollton is documented as the location of "Rising Sun Hall" near the riverfront in the late 19th century, which seems to have been a building owned and used for meetings of a Social Aid & Pleasure Club, commonly rented out for dances and functions. This is one possible inspiration for the legendary song "The House of the Rising Sun." Definite connections to gambling or prostitution, if any, are undocumented for either of these buildings, neither of which still exists. Most of Carrollton has long been ethnically mixed, with "free people of color" owning homes in other parts of the town before the Civil War.
