Cisterna di Latina Close Encounter Case

The Cisterna di Latina close encounter case is a highly disputed Italian trace report from August 1993. Usually tied to the Le Castella area near Cisterna di Latina, the case became known because residents reported a loud boom during the night and, by morning, irregular furrows and darkened ground had appeared on a dirt road and nearby property. Some treated the site as a UFO landing trace, while others argued the marks had nothing to do with ufology at all.

Cisterna di Latina Close Encounter Case

The Cisterna di Latina close encounter case is best understood as a trace-centered mystery rather than a classic witness-and-craft encounter. It is usually tied to the night of 10 August 1993 in the Le Castella area near Cisterna di Latina, in Lazio, where residents reportedly heard a loud boom and, by morning, discovered irregular furrows and darkened patches in the soil near a private property and dirt road. The case later entered Italian UFO catalogues, but even sympathetic modern retellings stress that no confirmed UFO was actually seen.[1][2][3]

That distinction matters.

Within this encyclopedia, the Cisterna di Latina case is important because it shows how a report can enter ufology through traces and inference rather than through a direct aerial observation. It also matters because it attracted police-scene attention, civil-protection notification, and later competing explanations that ranged from UFO landing traces to ritual activity to ordinary mechanical disturbance.[1][2]

Quick case summary

In the standard reconstruction, an unnamed local resident or merchant living in Le Castella was awakened during the night of 10 August 1993 by a powerful boom, described as similar to a jet taking off. He did not go outside immediately. The following morning, he discovered a network of irregular furrows, some of them several centimeters deep, cutting across a dirt track and extending into a vineyard or adjacent property. Parts of the disturbed soil reportedly looked darker or burned. Similar marks were later said to have been found on another nearby property as well.[1][2]

From there, the case split in two directions:

  • some observers treated the traces as possible evidence of a UFO landing or passage
  • others argued the marks were more consistent with human activity, possibly even a ritualized ground design, prank, or ordinary vehicle damage.[1][2]

That split has never been fully resolved.

Why this case matters in UFO history

The Cisterna di Latina case matters because it belongs to a particular kind of UFO file that is both attractive and fragile: the ground-trace case without a confirmed object. It was included in the Centro Ufologico Nazionale case table for 1993, which shows it entered the Italian ufological record, but its value has always depended more on interpretation than on direct observation.[3][4]

Historically, it is important because it combines:

  • a precise date
  • a known locality
  • reported environmental disturbance
  • local official attention
  • later ufological cataloguing
  • and a strong internal critique from later commentators who argued that the case may have had nothing to do with UFOs at all.[1][2][3]

Date and location

The date most strongly tied to the case is the night of 10 August 1993, identified in later retellings as the night of San Lorenzo. The location is Le Castella, a locality of Cisterna di Latina in the province of Latina, along the broader Appia corridor toward Velletri. Modern locality references confirm that Le Castella is a recognized area within the Cisterna territory, not an invented label attached afterward.[1][2][5][6][7]

This geographical context matters because the case was never a city-center event. It was rural or semi-rural from the start:

  • a dirt road
  • private land
  • scattered residences
  • and enough open ground for visible traces to become the focus of attention.[1][2][5][6]

Was there actually a UFO sighting?

This is the key problem in the entire case.

In the strongest surviving public summaries, no one is clearly said to have seen a UFO at the moment the traces were created. What witnesses reported first was a boom, and what they discovered later were marks in the ground. One later analytical retelling explicitly argues that the case should not really be classified as a second-kind close encounter at all, because there was no observed craft, no light, and no direct landing narrative, only the later interpretation of unexplained traces.[2]

That makes Cisterna di Latina a particularly useful case for your archive: it belongs in UFO history, but only with a strong editorial warning.

The furrows and the darkened soil

The most repeated physical details are the furrows and the darkened ground. In the later reconstructions, the furrows were:

  • several centimeters deep
  • irregular rather than perfectly geometric
  • spread over a section of about 50 meters
  • and at one point appeared to fork or diverge into a vineyard.[1][2]

Some descriptions say the overall pattern resembled a large inverted cross, though this is a later interpretive description rather than a neutral measurement. Inside the furrows, the soil was said to look darker, and in some retellings it seemed burnt.[1][2]

Those physical details are what pushed the case into both UFO and occult speculation.

The boom during the night

Another recurring feature is the boato — the loud explosive or jet-like sound reportedly heard during the night. According to the modern retellings, the sound was strong enough to wake the principal witness and at least some nearby residents.[1][2]

This matters because the boom is the only temporal anchor linking the unseen nighttime event to the traces discovered the next morning. Without it, the case would simply be a story about mysterious ground damage.

Official attention: Civil Protection, military contacts, and police

The later summaries state that the main witness alerted the Aeronautica, Protezione Civile, and the Scuola di Artiglieria di Sabaudia. They also say that the Polizia Scientifica from the Questura di Latina took photographs and sampled the allegedly burned soil.[1][2]

This is one of the reasons the case had enough seriousness to be remembered. However, an important caution is necessary: the modern public summaries do not provide a complete publicly accessible police or military report. So while official attention is part of the tradition, the case does not have the same documentary strength as a fully released file.

The Geiger-counter claim

Later retellings also say that visiting ufologists brought a Geiger counter to the site and reported weak traces of radioactivity. In the same chain of narrative, this was then interpreted in different ways: by ufologists as potentially anomalous, and by occult-minded locals as evidence the area was suitable for ritual activity.[2]

This is one of the least secure parts of the public case history. It survives in modern retelling, but without the kind of documented measurement record that would let it stand as strong evidence.

The occult / ritual interpretation

One of the most unusual things about the Cisterna di Latina case is that it did not develop only along a UFO line. Almost immediately, another explanation entered the story: that the marks might have been linked to black magic, satanic ritual, or some form of deliberate symbolic ground design. The later summaries say that a local woman with a reputation as a “maga” or fortune-teller claimed the traces resembled ritual activity and might have been intended to delimit an area for demonic evocation or a curse.[1][2]

This is important historically, even if it sounds sensational, because it shows that the case was never universally interpreted as a UFO event even in local folklore.

Why believers find the case persuasive

Supporters of a UFO-linked reading focus on:

  • the sudden nocturnal boom
  • the appearance of fresh ground traces by morning
  • the allegedly dark or scorched soil
  • the interest from police and civil-protection channels
  • and the fact that the case entered recognized Italian UFO catalogues.[1][2][3]

For believers, the argument is that something unusual happened in the night and left behind traces that were never convincingly explained.

Why skeptics push back

Skeptics have strong arguments here, and they matter more than in many better-known cases.

The main skeptical objections are:

  • no clear UFO was seen
  • the marks were irregular and could fit mechanical or human causes
  • the “inverted cross” description may reflect interpretation more than measurement
  • no strong public laboratory result is available
  • and one later review explicitly concludes that the case has nothing solidly to do with ufology.[2]

That critique is unusually important because it comes from a writer engaging the case from within UFO-history culture rather than from a hostile outsider. In other words, even some UFO-oriented commentary considers the case weakly founded as an actual close encounter.

The CUN classification problem

The Centro Ufologico Nazionale case table is especially useful here because it shows two related entries:

  • 10 August 1993, Cisterna di Latina (LT) with one case-type code
  • 24 August 1993, Le Castella di Cisterna (LT) with another case-type code.[3][4]

This suggests that the event either generated:

  • more than one related entry,
  • a later follow-up observation,
  • or a cataloguing split between the broader municipality and the specific locality.

That is a valuable clue, but also a warning. It shows the case history may have been more complex than the one popular summary now in circulation.

Was this really a close encounter?

Strictly speaking, not in the classic sense.

There was:

  • no clearly documented hovering craft
  • no direct humanoid encounter
  • no photographic sequence
  • and no secure contemporaneous aerial observation.

What we have instead is a trace case later interpreted as a possible UFO landing site. That still belongs in a close-encounter archive because UFO literature absorbed it, but it should be framed honestly as close-encounter-adjacent, not as a clean CE-II or CE-III.

Why the case remains unresolved

The Cisterna di Latina case remains unresolved because it is too weak to prove a UFO and too strange to disappear entirely.

On one side:

  • there was a loud reported nighttime sound
  • traces were found the next morning
  • official sampling is said to have occurred
  • and the case entered UFO catalogues.[1][2][3]

On the other side:

  • there was no confirmed object
  • no transparent public technical report
  • no decisive physical evidence
  • and strong non-UFO explanations remain plausible.[1][2]

That unresolved tension is exactly why the case still belongs in the archive.

Cultural legacy

The case has a modest but persistent afterlife in:

  • Italian UFO-case compilations
  • later CISU-adjacent commentary
  • local-memory retellings
  • and web-era discussion of ambiguous “landing trace” cases.[1][2][3][8][9]

It is not a famous global case, but it is the kind of small regional file that shows how UFO history often grows from traces, rumor, and uncertainty rather than from clean spectacle.

Frequently asked questions

What happened in the Cisterna di Latina close encounter case?

In the standard retelling, residents in the Le Castella area near Cisterna di Latina heard a loud boom during the night of 10 August 1993. The next morning, irregular furrows and darkened patches of soil were discovered on a dirt track and nearby land, leading some to speculate about a UFO landing while others proposed non-UFO explanations.[1][2]

Was a UFO actually seen?

No confirmed UFO sighting is part of the strongest public version of the case. The story is based mainly on the boom and the traces found afterward.[1][2]

Why did people connect it to UFOs?

Because the marks were sudden, unusual, reportedly darkened or burned-looking, and were later included in Italian UFO catalogues as a possible trace event.[2][3]

Were authorities involved?

Later retellings say that the Aeronautica, Civil Protection, the Artillery School at Sabaudia, and the Latina scientific police were notified or involved at some level, including photography and soil sampling. But no widely available public technical report has settled the matter.[1][2]

Is the case considered solved?

No. But it is also not considered a strong UFO case by many later commentators, because there was no direct aerial observation and the traces could fit non-UFO explanations.[2]

Editorial note

This encyclopedia documents the Cisterna di Latina close encounter case as a trace-centered and highly disputed Italian UFO file. It should be read carefully. The case is historically interesting because it entered UFO catalogues and reportedly drew local official attention. But it is weaker than classic close encounters because there was no clear observed craft, no stable witness narrative of a landing, and no decisive public evidence that the traces were caused by anything extraterrestrial. That ambiguity is not a side issue — it is the case.
