Roman Soldiers at Vindolanda Fort: Battling Parasites in Northern England
During their time at the fort of Vindolanda, located near Hadrian’s Wall in northern England, Roman soldiers faced a formidable enemy within their own bodies – parasites that significantly impacted their fighting fitness. A recent archaeological study jointly conducted by researchers from Cambridge and Oxford sheds light on the health challenges experienced by these ancient warriors.
According to Marissa Ledger, an archaeologist at McMaster University and co-lead researcher of the study, Roman soldiers at Vindolanda struggled with chronic gut infections caused by intestinal worms. These infections led to symptoms such as diarrhea, stomach cramps, and nausea, ultimately reducing the soldiers’ fitness for duty.
The study analyzed samples of sewer drain sediments dating back to the 3rd century CE, revealing a high prevalence of worm eggs in the ancient poop collected from the fort’s latrine drain. This evidence points to the presence of roundworms, whipworms, and potentially Giardia, a microscopic organism known to cause diarrhea.

Despite the presence of amenities such as baths, toilets, and drinking water at Vindolanda, outbreaks of parasitic infections were attributed to poor sanitary practices, including fecal contamination in food, water, and on the soldiers’ hands. This resulted in severe illnesses characterized by dehydration, fatigue, and weight loss.
Interestingly, the parasite profile at Vindolanda mirrors that of other Roman military sites, suggesting a common dietary pattern focused on pork consumption. In contrast, urban sites like London and York exhibited a more diverse range of parasites, including fish and meat tapeworms.
Overall, the research highlights the harsh realities of life for Roman soldiers stationed at Vindolanda, where frontier settlements faced the harshest hardships. Despite the modern perception of Roman hygiene, the historical evidence reveals a dirtier and more fecal-infested reality, emphasizing the challenges faced by ancient warriors in maintaining their health and fitness.
