The oldest structure in the world is a 23,000 year old stone wall, at a cave entrance, in Greece. It is known as the Theopetra Cave. Ireland oldest structure, New Grange, although older than the Pyramids, is still comparably young at an estimated 5000 years old.
Oldest written laws: Surprisingly examples of building laws and regulations survive that are almost as old as New Grange. This is the 3800 year old Code of King Hammurabi, from the Babylonian Empire, the empire was centred around modern day Iraq. The Code was a set of 282 laws which cover a range of sensitive issues, including: contracts, construction, property, marriage, family, injury, treatment of slaves and labour rates. They survive today on stone carvings and clay tablets. In fact we only have an incomplete set of the laws, as those between 66 to 99 are missing from the fragments/ tablets available.
