They are megalithic constructions only at Menorca Island. They had a clear funerary function. They had to do with Peninsular megalithic expressions -corridor dolmens- but constructive features show a technical progress in those of Menorca. Both constructions have a door as an access to the burial chamber, worked as a window on a stone. First navetas had an oval shape that makes us remember a tumulus.

The most usual shape for navetas is an inverted boat. That gives them their name.
They are chronologically prior to talaiotic culture and age. They are still built with big stones -orthostates- that cover their walls and are placed in a vertical position -as corridor dolmens-. This megalithic shape of building was later changed by a different one called cyclopean: it consisted of an horizontal fitting of middle-size stones.
List of well preserved navetas on the island is as follows:
- Naveta of Es Tudons.- The best known naveta on the island is very well preserved. It is 5,30 m. wide at its basis and 4,25 m. high. Through a little door we have access to a room ca. 1,50 m. long. Behind it, we find the main chamber with an eliptical plan of 7,50 m x 2,10 m. The cover is a lintel. At the first room there is an access to the upper one.
- Navetas of Biniac-L'Argentina.- Whole of two transitional navetas, since they are close to dolmens and are an intermediate step from dolmens and standart navetas.
- Navetas of Rafal Rubi.- Another pair of evolutioned navetas with an absidal plan and two levels separated by a file of flat stones as a lintel.
