It becomes difficult to relate the former history of the Azores (being discovered by the Portuguese in 1430s), with recent information about its dolmen constructions, especially when these display specific characteristics like entrances facing east (as it is common to the megalithic culture), building technology (overlay of enormous boulders), cup and cut marks applied to rocks and rock basins (called Bullauns in Ireland) of all sizes, as well as series of chaotic inscriptions. All these information is disturbing the picture already articulated.
