In 2021, cmp and SOT continued geophysical investigations at several archaeological sites in southeastern and central Mallorca, building on earlier campaigns from 2016–2018. The surveys combined magnetic prospection and ground-penetrating radar (GPR) at Es Velar (Santanyí), Castell de Santueri, Firella (both in Felanitx), and Can Moragues (Santa Maria de Camí).
The results revealed clear evidence of ancient settlement structures at Es Velar and a complex sequence of buildings at Castell de Santueri, while only limited and poorly preserved remains were detected at Firella and Can Moragues.
