Rocca di Grottammare

The remains of Grottammare's medieval fortress crown the hilltop borgo above the Adriatic. The settlement's earliest written records refer to the rocca, around which the town's walls and lanes developed.

Why it matters

The fortress links Grottammare's hilltop origins with its later life as a coastal stronghold and seaside town. Though fragmentary, its remains preserve the relationship between castle, borgo and coast.

What to notice

The ruin includes curved brick scarp walls, tower fragments with projecting brackets and machicolations, and two narrow openings associated with artillery. Aleppo pines now grow around the summit. From the hilltop, the old town and Adriatic coast form a broad panorama.

Context and history

The fortress may date to the ninth or tenth century; written references to Grottammare appear by the eleventh century. In 1248 Pope Innocent IV decreed its return to Fermo's sphere after the fall of Frederick II. Manfredi granted the castle and port to Fermo in 1259. In the fifteenth century, Francesco Sforza took the town; his son Sforza Secondo was born there, and Bianca Maria Visconti stayed in the fortress. During the War of Castro in the 1640s, Pope Urban VIII had the castle rearmed. A tower on the summit was partly demolished in 1766 and levelled in the early nineteenth century.
