Alexander the Great, the 4th-century BC Macedonian king who conquered the Persian Empire, reportedly had the most expensive funeral in history. His remains' location is unknown, but the extravagant funeral included a golden sarcophagus placed within another, transported in a golden carriage to Egypt over two years. The estimated cost, equivalent to $600 million today, reflects the opulence of the event. Summum, a Utah-based organization, offers mummification services at $67,000 for those interested in ancient burial practices.
