In Menorca and Majorca there are several dozen habitational and funerary naveta complexes, some of which similarly comprise two storeys.
[6] Navetas were first given their name by the rather imaginative Dr Juan Ramis in his book Celtic antiques on the island of Menorca (1818), from their resemblance to upturned boats.
[1][2] Although listed in the Spanish heritage register on 3 June 1931 (RI-51-0003442), the naveta d'Es Tudons was excavated and restored by archaeologist Lluís Pericot García in 1959–1960.
Various recovered objects like bronze bracelets or bone and ceramic buttons [4][15] are today on display in the Museu de Menorca in Mahón.
[16] The shape of the Naveta d'Es Tudons is that of a boat upside down, with the stern as its trapezoidal façade and the bow as its rounded apse.
The front, side walls and apse of the edifice consist of successive horizontal corbelled courses of huge rectangular or square limestone blocks dressed with a hammer[19] and fitted together without mortar, with an all-round foundation course of blocks of even greater size laid on edge.
[21] According to Phil Lee, the author of The Rough Guide to Menorca, folkloric memories of the navetas' original purpose may have survived into modern times, for the Menorcans were loath to go near these odd-looking and solitary monuments until well into the 19th century.
