The story
If you are standing here now, you are likely feeling the pulse of Naples. This square is a great, swirling intersection where the salt air of the Mergellina harbor meets the roar of the city traffic. At its center, a white marble mermaid rises from a tumble of rocks and sea creatures, her arm raised as if she is about to sing. This is the Fontana della Sirena, the Fountain of the Mermaid, and she is the perfect guardian for a place named after Jacopo Sannazaro.
Sannazaro was a man of the High Renaissance, born here in Naples in 1457. In a city that has always been a crossroads of cultures, he was a giant of literature—a poet and a courtier who served the kings of the House of Aragon. If you were a reader in the early 1500s, his name was everywhere because of a book called Arcadia. It was a dreamlike story that mixed prose and poetry, describing a lost world of shepherds and idyllic landscapes. It became a sensation across Europe, essentially establishing the pastoral style that writers would follow for the next two centuries.
But why this specific spot for his name? Sannazaro didn’t just write about Naples; he belonged to this shore. In the late 1400s, King Frederick the First gave him a villa right here in Mergellina. He loved this coast so much that he founded the church you can see sitting just a bit higher up the slope—Santa Maria del Parto—where his tomb remains today.
The square itself is younger than the poet’s legacy. It took its current shape during the late 19th century, a time when Naples was undergoing a massive urban redevelopment known as the Risanamento. This space was created to connect the elegant promenade of the seafront with the hills and tunnels that lead into the rest of the city. The Mermaid fountain wasn’t always here, either. She was sculpted by Onofrio Buccini in 1869 and originally stood near the central train station to welcome travelers. She was moved to this piazza in 1924, right when the nearby tunnel, the Galleria Laziale, was being completed to link this area to the district of Fuorigrotta.
Today, the square acts as a doorway. To your back is the sea and the old fishing harbor; ahead is the tunnel’s mouth; and all around you are some of the city's most famous pizzerias and kiosks. It is a place that never quite sleeps, filled with the smell of fried dough and sea spray.
Before you continue your walk, take a closer look at the fountain in the center. Most people notice the mermaid first, but look down at the base. You will see four creatures supporting her: a horse, a lion, a dolphin, and a turtle. See if you can spot the turtle—it is tucked away in the stone, a quiet, slow-moving reminder of the history that lies beneath the frantic pace of modern Naples.
