In 1835, when the Pemaquid Point lighthouse was built in Bristol, Maine, the American paint industry did not yet exist. Portland cement technology was still more than three decades away from reaching the United States, and prepackaged paint production would start even later. Yet the stone lighthouse, built utilizing the best technology of its time, endured severe coastal exposures for 172 years with only minimal maintenance.
