Theme: Cities Built on the Silver Trade
Silver reshaped these cities into imperial treasure houses and trade hubs. Potosí's mountain of silver funded the Spanish Empire and minted coins that circulated worldwide. Zacatecas and Guanajuato grew into colonial jewels on the back of Mexico's vast silver lodes, while Kutná Hora's medieval mines financed Bohemian kings, and remote Idaho City boomed briefly on American silver strikes.
