en.wikipedia.org/wiki/Roman_ruins_of_Milreu

The article's infobox says the site was "Abandoned ... 10th Century AD." That conflicts with current official heritage descriptions of Milreu.

The official Monumentos do Algarve page states that the Villa Romana de Milreu "reveals continuous occupation from the 1st century until the 11th century" and adds that the temple also served Islamic worship "until the 11th century." The national Património Cultural archaeological-sites page likewise describes Milreu as "inhabited continuously from the 1st century to the 11th century."

Because these official descriptions explicitly extend occupation into the 11th century, the claim that the site was abandoned in the 10th century is inaccurate.

In context, the article says a temple built in the 4th century "in the following century" became a Paleochristian temple. If the building was erected in the 4th century, "the following century" means the 5th century.

But the official heritage descriptions place the christianization later, in the 6th century. The Monumentos do Algarve page says the religious building was erected in the 4th century and was "Cristianizado no século VI". An official Milreu visitor-support PDF says the same: the temple dedicated to aquatic divinities "foi erguido no século IV" and "No século VI o edifício foi cristianizado."

So the chronology in the article is off by about a century: the temple was christianized in the 6th century, not in the immediately following century after the 4th.

The article says Milreu shows "continuous occupation until the 10th century." Official heritage descriptions instead place that continuity through the 11th century.

The Monumentos do Algarve page says Milreu "reveals a continuous occupation from the 1st century until the 11th century." The Património Cultural archaeological-sites page uses the same chronology, describing the site as "inhabited continuously from the 1st century to the 11th century."

Those official descriptions directly contradict the article's statement that continuous occupation only lasted until the 10th century.

This sentence states that Milreu was abandoned in the first half of the 10th century. Official heritage sources describe a later end date.

The Monumentos do Algarve page says the site shows continuous occupation from the 1st century "until the 11th century," and that the temple continued to serve worship in the Islamic period "until the 11th century." The national Património Cultural archaeological-sites page likewise says the villa was "inhabited continuously from the 1st century to the 11th century."

Those official timelines are incompatible with an abandonment in the first half of the 10th century.
