“The altar of the sea” (Altare del mare) is the first altar of the right aisle of the cathedral of Santa Maria della Marina. It is a commemorative work dedicated to Sciocchetti brothers: one was a pastor and the other one was a co-worker. They were so important for the navy of San Benedetto del Tronto. In this altar, in addition to a lunette by Don Luigi Sciocchetti, there is a beautiful bas-relief by the artist Aldo Sergiacomi that tells, through very interesting iconographic elements, the figures of the two brother priests. In November 1990 the roll of honor of the “Fallen civilians of the sea” (Caduti civili del mare) was placed there by Circolo dei sambenedettesi. There are listed all shipwrecks from the second half of the nineteenth century until the last decade of the twentieth century.
