San Marco is a seaside hamlet of Castellabate. It is older than Santa Maria di Castellabate. The Archaeological Museum of Paestum keeps many findings discovered here: it is very likely that the hamlet stands on the site of an ancient Phocaea "Citadel". Under Roman rule it was elected, by aristocracy, as summer resort: of the Greek-Roman splendour only the beautiful port remains. On the upper part of the coast (Castelsandra Hill) there is a natural park with lush vegetation. Sandy beaches "del Pozzillo” and "della Grotta"(which takes its name from the natural cave where some Paleolithic artifacts were found) are shared with Santa Maria.
The Church of St. Mark the Evangelist, built in 1915, is located in “Giuseppe Comunale" Square. The façade bears, in the center, the inscription Divo Marco Dicatum and the lion with the Gospel (symbol of St. Mark the Evangelist), on the left side the bas-relief of St .Antony and on the right side that of Saint Teresa. On each column capitals an Angel is depicted. A three-storey tower, with a square base of Romanesque style and a clock, stands out.
The "Torretta", which is located on the regional road 267, is a 17th-century fortified farmhouse owned by the Granito family. It was formerly the residence of some marquises and it was also used for the agricultural production, as the annexed warehouses, used to preserve the harvest, testify to. The Torretta, incorporated into the farm’s structure, has warning and defense function. It is also linked to legends about the “ius primae noctis” (Droit du Signeur) that, maybe, the Marquis exercised with the sailors' and local peasants’ wives. It is said that, during restoration works, the skulls of seven men was unearthed: they are supposed to have devised, in the first half of 1700s, a plan to kill the Lord, who had insisted on the “right” to take the virginity of a young girl named Teresa, wife of the farmer Cipullo.
The Torretta has also been the location of one of the scenes of the film "Benvenuti al Sud".
"Carlo De Angelis” Palace is a noble building located in San Marco. One of the characteristic features of the Palace is the entrance, made of Cilento’s stone: on the portal is placed an inscription dating back to the late 1800s. This epigraph reads literally: Inveni portum spes et fortuna valete sat me ludite nunc lusistis alios (I found the port, goodbye hope, farewell luck, you have cheated me enough, now deceive others). It seems that originally this epigram, whose author remains unknown, was an epitaph, a slogan written on a tomb. In fact, the whole area, where De Angelis Palace and adjacent buildings rise, houses a necropolis with approximately 150 graves, as estimated by the government department responsible for monuments and other treasures of Salerno.
The remains of a Greek-Roman port emerge from the waters of San Marco, near the modern port structure built in 1954. The first settlement of the town developed just around this structure. The port of San Marco, identified with the ancient Roman city of Erculia or Ercolam, was the main supply port for boats headed to Misenum, and military base or support site for the Imperial fleet. To confirm this hypothesis some finds, discovered in the waters of the port of San Marco in 1960s, of some lead anchors (dating from between the 1st and 2nd century AD) with the inscription “ter”: this designation indicates the type of ship to which the anchors were intended: the Triremes.
