Answer

Is it safe to build a house above an ancient cave in Mallorca?

Building above an archaeological site can be risky if the cave is affected by vibration, moisture or ground movement. In Mallorca, that is especially sensitive when a prehistoric burial cave lies beneath a new house. The key issue is whether proper archaeological checks, technical protections and long-term monitoring were put in place.
