Four museums in New Orleans and the Capital Park Museum in Baton Rouge will participate in Smithsonian magazine’s Museum Day Live! on Saturday.

Participating museums and cultural institutions nationwide will open their doors to Museum Day ticket holders free of charge for the day, encouraging support of these educational centers.

The four New Orleans museums are The Historic New Orleans Collection, 533 Royal St.; Longue Vue House and Gardens, 7 Bamboo Road; the Ogden Museum of Southern Art, 925 Camp St.; and the Southern Food and Beverage Museum and The Museum of the American Cocktail, 1504 Oretha Castle Haley Blvd.

To get a Museum Day ticket, visit www.smithsonian.com/museumday. One ticket provides museum access for two people to one participating institution.

As a Museum Day participant, THNOC will offer free admission (with download of an online ticket) to its Williams Residence Tour or the Architecture and Courtyards Tour.

The offer is good for one tour, both of which are offered at 10 a.m., 11 a.m., 2 p.m. and 3 p.m. on Saturdays.

The Williams Residence Tour showcases the French Quarter home of THNOC’s founders, General L. Kemper and Leila Williams. Built in 1889, the two-story townhome was purchased by the Williamses in the late 1930s as a commitment to the neighborhood’s preservation. They furnished it with items from their world travels. The tour offers not only a window into the lives of THNOC’s elegant founders, but it also features an enviable cache of internationally significant pieces.

The Architecture and Courtyards Tour illustrates the diversity of architectural styles seen throughout the Vieux Carré, showcasing the seven historical structures that make up THNOC’s Royal Street complex, including a Creole Cottage, an American side hall townhome, a Creole-Italianate townhome and three private courtyards.
