Belém Tower, Lisbon, Portugal

Ships leaving Lisbon once passed a small stone tower before meeting the wide Atlantic. That tower, standing on the bank of the Tagus River, served as both a guardian and a farewell. Say hello to Belém Tower—a fortress that watched Portugal sail into the Age of Exploration.
