Mallorca is an island located in the Mediterranean Sea, one of the Balearic Islands.
This arch is a natural geological formation. On coasts two different types of arches can form depending on the geology. On discordant coastlines rock types run at 90° to the coast. Wave refraction concentrates the wave energy on the headland, and an arch forms when caves break through the headland. When these eventually collapse, they form stacks and stumps. On concordant coastlines rock types run parallel to the coastline, with weak rock protected by stronger rock the wave action breaks through the strong rock and then erodes the weak rock very quickly.
