Mysterious Sea Bowls in La Palma

Summary Authors: Jose F. Arozena & Cadan Cummings

These circular or ovoid shaped holes of different sizes and depths are
called sea bowls. Mysterious in nature, their origin has been
hypothesized to be human made by the ancient inhabitants of the La
Palma island- the so-called Awaras- since their creation has not
been explained geologically. Several theories for their purpose range
from serving a role in regional fishing or livestock farming to
representing a part of sacred history for native populations. Located
adjacent to the sea which is historically used to wash sheep and other
livestock, the sea bowls could have served a role in bathing and
deworming cattle in summer months. This evidence is supported by their
names on marine maps stemming from livestock terms- such as “cattle
tip” shown in the images above. Alternatively, their orientation on
the horizon points approximately to where the Sun rises and sets during
the solstices. Whether a part of ancient livestock agriculture,
marking annual astrological events, or something altogether different,
these sea bowls in the volcanic basalt rock have endured the test
of time as their shape remains even after being covered by hightide
repeatedly for countless years.

Miguel Martin’s videos and podcasts in the Canarian prehistory magazine
