The world’s oldest wooden wheel has been around for more than 5,000 years
It was found in 2002, approximately 12 miles south of Ljubljana, the capital of Slovenia, and is now housed in the city’s museum. Radiocarbon dating was used to determine the wheel’s age, which is somewhere between 5,100 and 5,350 years old. Closer to home, these are the oldest tourist attractions in every state.
Incredible! I wonder how it was able to remain that way after all these years?
