Two churches in New Orleans. Old Ursuline Convent has 1 ticket or tour to book; St. Louis Cathedral has no online ticket listed. The table and the two notes below put them side by side; the full pages have what to see, the ticket and the timing for each.
A modest ticket covers the convent museum, the adjoining St Mary's Church and the formal garden; audio guides are included and guided tours run at set times for a small supplement. The site is on Chartres Street at the quiet end of the French Quarter, five minutes from Jackson Square, so there is no transport cost. Walking tours of the Quarter include the convent and cost several times the entry, usually adding the cathedral and the Cabildo.
Saint Louis Cathedral stands on Jackson Square in the French Quarter of New Orleans, facing the Mississippi River, and entry is free, with self-guided tour leaflets available for a small donation. It is the oldest cathedral in continuous use in the United States and the symbol of New Orleans. Walking tours of the French Quarter, including history and ghost tours, always include the cathedral along with the Cabildo and Presbytere museums flanking it, the Pontalba Buildings, the French Market and Cafe du Monde.
