Question

Where were some of the largest collections of iron tools found?

Answer 1

Some of the largest collections of iron tools found in the megalithic burials. While some of the megaliths can be seen on the surface, other megalithic burials are often underground. Megaliths (very big stones) were carefully arranged by people and were used to mark burial sites. The practice of erecting megaliths started about 3000 years ago.
