Today's stop in St. Augustine is Flagler College, the former Ponce de Leon Hotel, built by Henry Flagler as an exclusive resort hotel in the 1880's. Flagler was co-founder of Standard Oil, and was a millionaire developer who also built the railroad in Florida that went down to the Florida Keys. His friends included Tiffany for the stained glass, and Thomas Edison for the electricity. And the twin towers of the hotel were water storage tanks providing water to the hotel rather sourcing St. Augustine water. St. Augustine water smelled strongly of sulphur. Today this is a private college.
