The tribe maintains a cultural center and museum in Robeline, Louisiana. The center is about five miles north of
Los Adaes State Historic Site, an early 18th-century
Spanish mission and ancestral village of the Adai Indians. The museum houses hundreds of artifacts from the tribe's history. Among its artifacts are several gourd rattles that were carved, painted or decorated with beads and used in both prehistoric and modern ceremonies, as well as prehistoric containers for carrying food, water and herbs. Prehistoric cooking utensils, baby rattles and toys, war breastplates and traditional cradle boards are also on display. Many of the artifacts were recovered in 1995 from the Los Adaes Station and in conjunction with Northwestern State University. The tribe hosts an annual
powwow each October at its 80-acre ceremonial grounds in Robeline. Nearly 3,000 visitors attend the powwow making it the largest festival in Robeline and the surrounding area. Each Mother's Day, the tribe hosts a ceremony to honor their ancestors at St. Anne's Catholic Church and cemetery in Robeline. This tradition was taken from
St. Augustine Parish (Isle Brevelle) Church, which hosts a similar ceremony on All Saints Day. Historically, St. Anne's Catholic Church was part of the St. Augustine Parish. On March 11, 1856, the mission of St. Augustine at
Isle Brevelle was decreed by Bishop Auguste Martin to be a parish in its own right and assigned Fr. Francois Martin to be its first resident pastor.
St. Augustine Church (also known as the Isle Brevelle Church) expanded to serve four other churches in the area,
St. Charles Chapel at Bermuda,
St. Joseph's Catholic Mission at Bayou Derbonne,
St. Anne Chapel at Old River, and
St. Anne Church (Spanish Lake) serving the Adai Caddo Indians. == Notable people ==
