The Treasury, or Al Khazna. It is almost 40 meters high and intricately decorated with Corinthian capitals, friezes, figures and more. The Treasury is crowned by a funerary urn, which according to local legend conceals a pharaoh’s treasure. Although the original function is still a mystery, The Treasury was probably constructed in the 1st century BC. The Treasury consists of two floors with a width of 25.30 meters and a height of 39.1 meters. The purpose of the Treasury is unclear: some archaeologists believed it to be a temple, while others thought it was a place to store documents. However, the most recent excavation here has unearthed a graveyard beneath the Treasury.
