As I had noted in an earlier post, different methods have been adopted in different countries in ancient times, to move large objects. The 80-ton stone placed on top of the Brihadeswara temple in Thanjavur was moved from a quarry 200 km away, with the help of elephants and logs. A 200-ton stone was moved by the Chinese to the Forbidden City in Beijing by rolling it over ice in winter.
Recently, a 340-ton boulder was transported over 100 km, in 12 days in California. No elephants were necessary. They used a 200 feet long trailer. This feat will now feature in the Guinness Book of World Records. (source)
