The chapel has a simple rectangular aspect, with a portal and central windows, surmounted by a belfry. Inside, what makes it valuable and perhaps unique church of Morciano is the presence of a huge monolith, an authentic menhir of local marble, painted on whose front plate is a sixteenth-century Madonna and Child. The monolith has come to light in the recent years of the twentieth century as a result of a conservative intervention carried out by the Pro Loco "Torre Vado". Below the fresco are visible traces of color dating back to the classical period of Byzantine art in Salento (900-1000 AD). Depicted in the hand of the Child are three arrows (a clear reference to the SS. Trinity) symbolizing the divine love for humanity on earth.
