It has been a very long but hopefully exciting day exploring the core of Buenos Aires. You are now back at Puerto Madero where your walking tour began. Reward yourself with cocktails and dinner at one of the fine riverfront restaurants occupying the old warehouses. In the foreground is the ARA Uruguay. This Argentine Navy schooner was launched in 1874, qualifying it as South America’s oldest surviving gunboat. Her illustrious history ended in 1926. ARA Uruguay is permanently moored at old Dock 4 as a museum ship.
