The same expedition as in Berlitz's book (Above).
By 1981 an expedition lead by Pippo Cappellano found some mysterious basaltic ruins on the ocean
floor near the coast of Lanzarote.
At a depth of about 50 feet and over an area of 900 square feet, they found large flat stones that
look like they were carefully put into place.
These blocks were followed by wide stone steps. But that’s not all: an undersea wall also was disco-
vered which was formed by recular triangular blocks.
Mr. Cappellano and the structures found
undersea; as all good places where hypo-
thetic Atlantean buildings made of basalt
(...) have been found, also Tenerife has
its own misterious "constructions".
INFO: The basaltic rocks can form geometric structures when suffer high temperatures and pressures, as per example the formations of North Ireland.
