Belém Tower, or the Tower of St. Vincent, stands triumphantly on the banks of the River Tagus. This 16th-century keep is an icon of Lisbon, and a must-see while you're in the city.

With your digital Belém Tower tickets, you'll gawp up at the Manueline tower that helped protect the city for centuries. Admire its exquisite architecture decorated with sculptures, pillars, arches, gargoyles, and cupolas.

Across the four-floor interior, you'll see old window cannons and climb spiral staircases. Your Belém Tower ticket grants you access to the Governor’s and King's Chambers, the Audience Room, 16th-century vaults in the Chapel, as well as one of the best views in Lisbon from the Tagus.
