Why is "Cantabrian stelae" trending?

Wikipedia Overview

The Cantabrian stelae are monolithic stone disks of different sizes, whose early precedents were carved in the last centuries before the romanization of Cantabria in northern Iberian Peninsula. Cantabrian stelae include swastikas, triskeles, crosses, spirals, helixes, warriors or pre-Roman funerary representations among their usual ornamentation. The most famous is called Estela de Barros which can be visited in the Parque de las Estelas in the town of Barros, in Los Corrales de Buelna. This stele is part of the current coat of arms of Cantabria and the meaning of tetraskelion would be related to solar worship. The Barros stele giant size represents the main difference to the smaller stelae found in other parts of northern Spain. In addition to the Estela de Barros, we can see another larger, fragmented stele in the Parque de las Estelas.
