Where was The Head filmed?
2020 Spanish mystery thriller television series
Wikidata records no filming location for The Head (2020–) at all, not a place, not even a country. There is nothing to pin, and this page says so rather than guessing.
Why there is no pin
Its Wikipedia article also says it was filmed in Canary Islands, Iceland, Tenerife, without naming a place, so it is not on the map.
