According to new research, an ancient Crate-like object found in Czech Republic may be the world’s oldest known wooden structure. Using tree-ring dating techniques, researchers have revealed that the oak wood used to make it was cut around 7,275 years ago.The rings on the trunks helped researchers to estimate the exact age of the wood.  Despite the waterlogged conditions, the condition of the wood was remarkable. Comparing the construction techniques with examples of woodwork from bronze and iron ages increases the admiration for such perfection.
