Cyprus Peninsula Was Once Two Islands, NASA Satellite Images Show

The Akrotiri Peninsula, the southernmost tip of Cyprus, began as a separate island that was later tied to the main island by two natural land bridges, according to NASA's Earth Observatory. The agency published Landsat 8 images of the area taken on Oct. 10, 2026, along with an account of how the landscape formed.

The same landscape is tied to well-known local stories about snakes and cats, and to a flamingo population that NASA says has dropped sharply in recent years, citing news reports.

How the peninsula took shape, step by step

• About 90 million years ago: NASA says Cyprus began forming in the Late Cretaceous, when molten rock poured from the seafloor and hardened into new oceanic crust. Tectonic forces later pushed parts of that rock upward, and it emerged as a rugged island of ophiolite, a green-mottled rock said to resemble snakeskin. Remnants of that island are still visible in the dark rocks of the Troodos Mountains.
• The Miocene: Younger layers of chalk, limestone, marl and other marine sedimentary rocks built up around the island. During a later period of geologic uplift, this material became a second, smaller island to the south.
• About 50,000 years ago: The western land bridge, called the Kouris River tombolo, began to develop from gravels and sands deposited by a river. Sediment flowing into the channel between the two islands mixed with marine sediments, building deltas and eventually two tombolos.
• Within the past 2,000 years: According to geologists cited by NASA, the eastern tombolo extended south from Cyprus and cut off the Mediterranean Sea from what is now Akrotiri Salt Lake. The lake had once been an arm of the sea.
• The fourth century: By legend, a drought-era surge in snakes led Empress Helena, mother of Constantine the Great, to order shiploads of cats from Egypt. NASA presents this as legend, not documented fact.
• 2025: News reports cited by NASA say the number of wintering flamingos at the lake fell to 30 birds.
• Oct. 10, 2026: Landsat 8 captured the images showing the peninsula's sandy edges and the lake between the two land bridges.

A lake that fills and dries with the seasons

NASA describes Akrotiri Salt Lake as a coastal lagoon whose water levels change markedly through the year. It typically fills in late autumn and winter and dries out in summer. That winter water has historically drawn overwintering flamingos, averaging about 4,000 birds, which feed on fairy shrimp. The shrimp are rich in carotenoids, the colorful substances that give the birds their pink color.

Snakes, cats and a monastery

NASA notes that in antiquity Cyprus was called Ophiousa, or “land of snakes,” probably because of its many blunt-nosed vipers. In the legend, the first cats were released in a snake-infested area on the southeastern part of the peninsula. The area became known as Cape Gata, which means Cape Cat in Greek.

The Holy Monastery of St. Nicholas of the Cats still stands there. According to the legend, monks encouraged the arriving Egyptian cats to hunt snakes. NASA says a handful of nuns now live at the monastery and, according to the St. Nicholas Center, care for hundreds of cats. The agency adds that Cyprus today has more than one million cats, roughly one for every person.

Why it matters: a landscape's origins and a changing wetland

For readers, the images are a reminder that a coastline can have a long and surprising history. A peninsula that looks like a single piece of land on a map is, according to NASA, the product of two islands of different ages and rock types, joined by sediment over tens of thousands of years.

The flamingo figures show that a wetland shaped over that long span can change quickly in a short one. NASA reports a fall from an average of about 4,000 wintering birds to 30 in 2025. The agency's account does not explain the cause of the decline, and the figure comes from news reports rather than a NASA measurement.

The story is a feature built on satellite imagery and published geological references, not a new scientific study. The timeline for the land bridges relies on estimates from geologists, and the cat story is a legend.
