The historical offerings of The Historic New Orleans Collection include not only its artifacts but also its architecture. Its building at 533 Royal St. in the French Quarter includes a secluded courtyard reflecting the years when New Orleans was under Spanish rule, from 1762 to 1802. The Collection’s Concerts in the Courtyard series provides an entertaining opportunity to spend a few hours relaxing in the courtyard. This year’s series opened Sept. 18 with a performance from Gal Holiday and the Honky Tonk Revue. The series will continue one Friday a month, from 5:30 p.m. to 8 p.m., with Banu Gibson on Oct. 16, and Little Freddie King on Nov. 20. Admission is $10, free for THNOC members, and includes three beverages.
