It is dedicated to Saint Thérèse of Lisieux, also known as "The Little Flower", a French Carmelite nun who is widely venerated in the Catholic Church. The basilica was built in the early 20th century, after Saint Thérèse's canonization in 1925.

The basilica is a prominent example of the neo-Byzantine style of architecture, featuring a large central dome, intricate mosaics, and ornate stained glass windows. The interior of the basilica is adorned with a wealth of artistic and religious treasures, including murals, frescoes, and sculptures. One of the highlights is the reliquary containing the remains of Saint Thérèse, which is enshrined in the crypt beneath the basilica's altar.

The basilica is a popular destination for Catholic pilgrims, who come to pay homage to Saint Thérèse and seek spiritual inspiration. Visitors can explore the basilica's various chapels, view exhibitions on the life and teachings of Saint Thérèse, and attend daily Mass and other religious services. The site also includes a museum dedicated to the life of Saint Thérèse and her family, as well as a gift shop and café.
