La Coruna is a busy port on the Atlantic Ocean that provides a distribution point for agricultural goods from the region. It was the arrival of democracy in Spain after the death of Francisco Franco that caused a major growth in the city. The city is the site of the Roman Tower of Hercules, a lighthouse that has been in continuous operation for nearly 2,000 years. The city is also well-known for its characteristic glazed window balconies, called galerías.
