Why California’s Most Famous Mansion is Totally Forbidden

Hidden behind an iron fence in Eureka, California, the Carson Mansion is a Victorian house built between 1884 and 1886 by lumber baron William Carson. Known as the second most photographed private residence in America, the mansion cost millions to build and employed over a hundred craftsmen. It was constructed to reflect the grandeur of the redwood empire Carson created, attracting crowds since its completion. Today, the mansion is privately owned by the Ingomar Club, maintaining the interior in nearly original condition since 1950, with no public tours allowed. In 1974, even a California state official was denied entry during an official visit. This episode traces Carson's life, the fortune behind the mansion, and examines why it remains largely inaccessible after more than 140 years. #ItsHistory #CarsonMansion #VictorianHistory Learn more about your ad choices.

Why Chicago's Lighthouse is Totally Forgotten

A quarter mile east of Navy Pier, the Chicago Harbor Lighthouse has been guiding ships into one of the busiest ports on the Great Lakes since 1893. It features a gold-medal Le Paute lens from Paris and has housed keepers living in near-total isolation. Since its automation in 1979, the lighthouse has been abandoned, quietly rusting with no agreement on who should restore it. The Le Paute lens, one of the finest optical instruments ever installed in an American lighthouse, took a century to reach its destination, and the tower it left behind may not last much longer. #ItsHistory #Chicago #Lighthouse Learn more about your ad choices.

Why San Francisco was built on Hundreds of Shipwrecks

In the wake of the California Gold Rush in 1848, San Francisco faced an influx of vessels, many of which were abandoned by their crews. With no one to sail them home, these ships were left to deteriorate in Yerba Buena Cove. To manage the rapid growth, San Francisco made the drastic decision to sink these ships and build over them, creating a unique urban landscape. Today, it's estimated that between 50 and 200 ships, including the illustrious Niantic—once the finest hotel in San Francisco—remain buried beneath the city streets. #SanFrancisco #GoldRush #ItsHistory Learn more about your ad choices.
