In a time long ago in Hawai’i, sugar was a huge industry on the islands. This monument is a memorial to those days when Kōpa’a (sugar) was King. The huge gears were used to grind the raw sugar plants down, then heated and ground down more to produce various sugar varieties. Only a few plants are still operational anymore. Since then the industry has moved to other countries and only the shell of the factories remain. Sugar Mill Road is beautifully maintained with public access to the beaches.
