Answer  Explanation 

ANSWER: Graves surrounded by big stones

The Iron Age of the southern peninsula is often related to Megalithic Burials. Megalith means Large Stone. The burial pits were covered with these stones. The megalithic culture is mostly known for its burials, which have been generically termed megaliths (lit. = big stones), even when the big stones are not associated. These burials are marked by an abundance of iron tools and a Black-and-Red pottery.
