Lost Roman forts discovered using Cold War spy satellites

Published

on

A study of declassified imagery taken by Cold War era satellites during the 1960s and 70s has led to the discovery of 396 previously undiscovered Roman forts.

The forts are spread across the Syrian Steppe in what is now Syria and Iraq to protect the eastern provinces from Arab and Persian incursions.

According to the researchers, the forts are in a region where a proposed defensive line of 116 forts were identified in an aerial survey conducted by Father Antoine Poidebard in 1934.

“Since the 1930s, historians and archaeologists have debated the strategic or political purpose of this system of fortifications,” says lead author of the research, Professor Jesse Casana from Dartmouth College, “but few scholars have questioned Poidebard’s basic observation that there was a line of forts defining the eastern Roman frontier.”

In a study published in the journal Antiquity, a team from Dartmouth College studied the declassified spy satellite imagery which formed part of the first spy satellite programme’s to determine whether Poidebard’s findings were accurate.

Using the forts found by Poidebard’s as a point of reference, the study revealed 396 new fort locations in a landscape that has been severely impacted by modern-day changes in land-use. The forts were found throughout the region spanning from the east to the west, contradicting the theory that they formed a north-south border wall.

Instead, the study suggests that the forts were constructed by the Romans to promote inter-regional trade, safeguarding caravans journeying between the eastern provinces and non-Roman lands, and enabling communication between the eastern and western regions.

Crucially, this suggests that the boundaries of the Roman World were more flexible and inclusive than previously thought. It’s probable that the eastern Roman frontier wasn’t a constant hotspot of violent conflict.

Although the Romans had a strong military presence, they also placed importance on trade and communication with regions beyond their direct rule. Consequently, this revelation could significantly reshape our comprehension of life on the Roman frontiers.

Speaking to HeritageDaily, Professor Jesse Casana from Dartmouth College, said: “We were only able to confidently identify extant archaeological remains at 38 of Poidebard’s 116 forts. In addition, many of the likely Roman forts we have documented in this study have already been destroyed by recent urban or agricultural development, and countless others are under extreme threat.”

Archaeologists excavate medieval timber hall

Archaeologists from the University of York have returned to Skipsea in East Yorkshire, England, to excavate the remains of a medieval timber hall.

Recent excavations unearthed a timber hall measuring 5 metres wide by 16 metres long, which was surrounded by a large ditched enclosure.

The size and shape of the hall is marked by post holes, which the team plan to excavate further to provide new insights into the hall’s purpose and setting in the surrounding landscape.

The hall sits adjacent to a 13-meter-high mound, once presumed to be a motte and bailey castle. However, carbon dating has since revealed its age to be 1,500 years prior to the Norman Conquest era from during the Iron Age.

Dr Jim Leary, from the University of York’s Department of Archaeology, said: “The unearthing of timber buildings dating to the period between the collapse of the Roman Empire and the arrival of the Vikings, a time often referred to as the Dark Ages, is an incredibly rare and significant find.

“The discovery at Skipsea is particularly interesting because we know that the area was in the hands of the last Anglo-Saxon King of England, Harald Godwinson, and then later, after the Norman Conquest of 1066, it became the estate centre of the Lords of Holderness.”

Skipsea was once home to three freshwater lakes, Skipsea Bail Mere, Skipsea Low Mere, and Skipsea Withow Mere, linked to the River Hull through a network of tributaries. These lakes (long-vanished), began 10,000 years ago during the Mesolithic period, and continued into the medieval period.

The lakes were a constant draw to population groups throughout history, which has provided archaeologists with Mesolithic stone tools, animal remains, bone harpoons, and Bronze Age buildings and trackways.

Archaeologists find traces of Gloucester’s medieval castle

Published

Archaeologists from Cotswold Archaeology have uncovered traces of Gloucester’s medieval castle in Gloucester, England.

The castle was first constructed during the Norman period as a simple motte and bailey. Over the centuries, various additions and periods of reconstruction extended the footprint of the castle, which by the 13th century became a royal residence for nobility and English kings.

Between the 15th century and 17th century, the castle went into decline and much of the stonework from the fortifications were used to construct roads and buildings within the city centre, leaving only the keep which was used as a gaol (prison).

In time, the keep was considered to be unsuitable and its demolition began in 1787, leaving no visible remains of the castle.

During development works in the south-west of Gloucester city centre, archaeologists from Cotswold Archaeology have uncovered traces of the castle beneath the basketball court of the former HMP Gloucester.

A number of trenches revealed medieval structural remains that archaeologists have interpreted as forming part of a masonry causeway or bridge structure. This provided access to the castle across its inner defensive ditch and continued north-east onto Castle Lane.

Excavations also found subsequent demolition and robbing of stonework, evidenced by the infilled castle ditch, and comprised cultivation soils of the Castle Gardens, which occupied this area from the later 18th century through to the mid-19th century.

In addition, a stretch of Post-medieval wall relating to the gardens was identified, which corresponds to a boundary shown on early and mid-19th century maps.

According to the archaeologists: “The results highlight that significant archaeology continues to survive at a relatively shallow depth, enabling us to trace historic land use and landscape change within this part of the city across many centuries.”
