Replica of a small 16th century 27 meters (88ft) Portuguese Nau.
After its invention and development in Portugal, naus became their first choice for exploration, trade and naval warfare. Later adopted by every other state in Europe and Asia, becoming the worldwide 1st choice type of vessel during the 16th, the 17th, and the 18th centuries.
The largest ones built in Portugal reached over 60 meters (197ft) long.
Though the European discoveries are often overstated by including places that were already inhabited by non-Europeans, the actual discoveries (meaning, islands never inhabited by people, or by people that had long died out) are extremely impressive.
