Friday, 7 April 1995 - Explored Guanajuato a beautiful colonial mining city built on silver and gold wealth. Stayed at the Hotel Santa Fe near the central plaza, wandered narrow streets and tunnels carved into the hillside that serve as roads, enjoyed the lively Jardín de la Unión with evening music, and visited the historic Hacienda de San Gabriel de la Barrera with its 17th-century gardens and European furnishings.
