Source-derived summary

San Giovanni di Posada (Latin: Portus Luguidonis or Portus Liquidonis) is a frazione and small village in Sardinia, Italy, on the Tyrrhenian coast of the island, in the territory of the comune of Posada.

Formerly known as Marina di Posada, it underwent rebuilding in the 1970s as an residential village for tourism.

Its history goes back to the Roman harbour (named "Portus Luguidonis" - presumably located in the little bay in front of the ancient church of St. John), from where the Romans entered inner Sardinia. Through this harbour passed all the goods to or from Rome, but all the cargo was carried by small and light ships directed to Olbia (some 50km north), where bigger ships would have trafficked with Ostia. Traffic was supposedly intense, Sardinia bearing the sobriquet "the granary of Rome".

In the immediate surroundings, it is supposed there was a temple in honour of Feronia, an Etruscan deity, goddess of the waters; this would prove the presence of Etruscans in this area at the time of Nuragici people. A similar cult of Feronia is reported on the Italian mainland at least in two places: in Fiano Romano (near Rome), and in Terracina, some 120km south of Rome.

It is one of the main tourist destinations of Sardinia, has a long beach (more than 15km of white sand) and a system of rivers of biological importance. A part of this territory is going to be formally protected in the near future with the creation of a nature park (Parco Fluviale).

Editorial summary

“San Giovanni di Posada” enters the record as human settlement in Italy. Crown Archives preserves that source wording while asking what Giovanni, Posada and human can confirm, complicate or overturn.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 253-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Giovanni, Posada and human.
Editorial analysis

Why this record matters

“San Giovanni di Posada” is worth following because a concise public description often conceals a longer documentary argument. Here, Giovanni, Posada and human provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q7414251. Authority coordinates are 40.618, 9.747. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
