Aztec ruins unearthed in Mexico

Archaeologists working in Mexico City have discovered an Aztec monolith, the most important ruins of the ancient civilisation to be found in decades.

The monolith and an altar, dating from the 15th Century, were unearthed in the very heart of the busy capital city.

The city's mayor described the discovery as the biggest in almost three decades.

I don't know about you, but of all the ancient civilisations, the Aztec's seem to pique my interest more than the others, apart from the Egyptians of course!
