A naviforme was a prehistoric boat-shaped house built on the Balearic Islands of Spain. The hut-like buildings date to the Early Bronze Age or the Pretalayotic Period. The building was generally large and had strong walls. It had dual functions for productive activities and living spaces. Examples of Naviformes are found in various villages but good examples have been excavated at Boquez, Sa Vall, and Son Mercer de Baix.
