This consciously excludes ruins of limited height and statues. The list also excludes:

Dates for many of the oldest structures have been arrived at by radiocarbon dating and should be considered approximate.

The following are amongst the oldest buildings in the world that have maintained the requirements to be such. Occupation sites with older human made structures such as those in Göbekli Tepe do exist, but the structures are monuments and do not meet the definition of building (which can be seen above).

The structure is a stone wall that blocked two-thirds of the entrance to the Theopetra cave near Kalambaka on the north edge of the Thessalian plain. It was constructed 23,000 years ago, probably as a barrier to cold winds.
