Commissioned between 1714 and 1725 by the Confraternity of the Most Holy Lady of the Annunciation, it soon became a place of miracles, such as the apparition of the Virgin of the Seven Veils to Alfonso Maria de’ Liguori in 1731 and the miracle of Our Lady of Sorrows which put an end to the cholera epidemic of 1837. Since then the people of Foggia have been looking with compassion and faith at this temple, which was then raised to the status of a minor basilica.

Although it retains fairly simple, straightforward architectural features, it remains baroque in its inspiration. On the façade, the vertical development is stressed by the staircase that meets at the entrance. The sides of the portal are richly sculpted and decorated. The interior is in the shape of a Latin cross with one nave only.

The decorative pattern, outstandingly baroque in style, has been restored several times over the years. Currently there are three altars: the high altar, with valuable marble inlays and a pillared canopy, is dedicated to Saint John the Baptist; the other two, in the chapels of the transept, are dedicated to the miraculous cholera-ridding Lady of Sorrows and to the Sacred Heart, respectively.
