The building is located in the surroundings of the famous plaza, it was designed by the architect F.A. Picchiatti, and was carried out between 1688 and 1697 by Marziale Desiderio from Amalfi, a dome and vault expert builder. The church was later consecrated in 1723, by bishop Michele Vandenejnde. It was placed above the bishop’s church, built over a previous religious structure in 1596, when the bishop’s palace was transferred there from the head office of Saint Constance, patron of the island due to the frequent dangerous Turkish raids. In that occasion, Saint Constance’s relics were also brought there. In the plaza, due to the good church angle-shot perspective, it is possible to visualize the successful structural and architectonical link between the seventeenth century façade, the central cupola and the vaults movements of the lateral chapels. The façade is baroque and the pinnacles, the vaults and the cloves are not at variance from the sixteenth tradition, while the covers represent a unique example, standing out from the repetition of contemporary schemes. The plant of the church is like a Latin cross and in the interior, it is jointed in 3 naves, with a cupola at the central nave junction with the transept.

The two lateral naves present four quadrangle chapels per side. The main entrance is characterized by a wooden portal dating back to the eighteenth century. The glass partition over the portal representing Jesus Resurrection, and the ones over the main nave symbolizing the seven sacraments are modern and date back to 1973. The altar in polychrome marbles, in the middle of the presbytery, was carried out in the seventeenth century. The altar and choir flooring was done with roman marble, using African marble marquetry, antique yellow and saravezza, recovered during the excavations of the Bourbons in 1759. The altar grades, on the contrary, are covered by marble slabs, obtained from the shaft of antique roman columns. There is also a big golden organ, dating back to the beginnings of the nineteenth century, aloft at the back of the altar, while at the bottom there are three tomb stones, with polychrome marble decorations, dedicated to the bishop of Capri Francesco Antonio Boccus, to monsignor Serafino Cimmino, and to the parish priest of Capri Giuseppe De Nardis. On both sides of the presbytery there are corridors that lead to the sacristy. On the one on the left, where the statue of Saint Constance stands, carried out in silver and decorated with sapphires, garnets and (beryl?) , there is a spiral staircase that leads to the roof. The altar in the middle of the left transept, contains besides the relics of the patron, represented on the above painting of G. Farelli in the moment  of  chasing the pirates. Finally, between the ornaments of the church, there are two antique golden consoles where a crib representation and a crucifix in glass caskets rest.
