Study Challenges Prehistoric Origin Theory for Malta’s Ancient Cart Ruts
New doctoral research suggests the mysterious stone tracks in Malta likely date to the Classical period, not the Bronze Age.

Key points
- Researcher Joel Grima argues evidence supports a post-prehistoric date for the Maltese cart ruts.
- The study analyzes 2,628 distinct tracks across more than 200 sites in the archipelago.
- Previous assumptions of a Bronze Age origin are described as indirect and circumstantial.
A new study published in the Journal of Archaeological Science: Reports challenges the long-held belief that the mysterious cart ruts in Malta are prehistoric. According to Gizmodo, doctoral researcher Joel Grima argues that the evidence points to a Classical period origin instead.
Grima, a PhD student at the University of Malta, initially favored a Bronze Age timeline for the tracks. However, he stated that the volume of evidence swayed him toward a later date. He notes that much of the supposed evidence for a prehistoric age is indirect and circumstantial.
Context and Background
The Maltese archipelago contains thousands of deep grooves etched into bedrock, resembling a railway network. These features have puzzled archaeologists for centuries due to their unusual appearance and density. Grima’s research focuses on 2,628 distinct tracks found across more than 200 different sites.
The total length of these tracks adds up to roughly 31 miles, or 50 kilometers. The largest cluster contains over 250 pairs, totaling 3.7 miles when laid end-to-end. This density is rivaled by few other locations, given the small size of the islands.
Physical Characteristics
Each groove can reach depths of up to 23.6 inches, or 60 centimeters. The distance between paired tracks ranges from 43 to 59 inches, or 110 to 150 centimeters. Some tracks appear connected like a railway network, while others trail randomly into the sea.
Cart ruts are a global phenomenon, with similar tracks existing in Europe, Asia, and North America. However, those instances are often found within urban archaeological sites, making them easier to date and contextualize. The Maltese ruts remain unique due to their sheer number and isolation.
What should you do?
Readers interested in archaeological developments should monitor peer-reviewed journals for updates on dating methodologies. Professionals in heritage management may need to review preservation strategies based on revised historical timelines. Academic institutions should track how new evidence shifts consensus on local prehistoric narratives.
What to do and how to stay safe: Joel Grima
- Review recent publications in archaeological science journals for updates on dating methodologies.
- Consult primary source materials rather than relying solely on popular media summaries.
- Monitor official statements from the University of Malta regarding ongoing doctoral research.
- Check with local heritage agencies for changes in site preservation guidelines.
