A Historical Passageway

The Bourbon Tunnel was envisioned by King Ferdinand II of Bourbon as a secret route connecting the Royal Palace to the city's military barracks. Designed by architect Errico Alvino in the 19th century, the tunnel later became a critical shelter for Neapolitans during World War II.
