QUẢNG NINH — Authorities at the UNESCO-recognised heritage Hạ Long Bay have been conducting solutions to preserve the natural wonder of thousands limestone islands and islets, forming the spectacular seascape of the property.

However, after millions of years of formation, a multitude of limestone islands and towering limestone pillars rising from the sea now are at the risk of collapse and landslides.
