Tower of Belém
From Conservapedia
The Belem Tower was built in 1515 as a fortress to guard the entrance to Lisbon's harbor, it was the starting point for many of the voyages of discovery, and for the sailors it was the last sight of their homeland. It is a monument to Portugal's Age of Discovery, often serving as a symbol of the country. Facing the river are arcaded windows, delicate Venetian-style loggias, and a statue of Our Lady of Safe Homecoming, a symbol of protection for sailors on their voyages.[1]
