This is the fortified Spanish villa that once housed leading members of the infamous Kinahan Cartel. Tucked away in a 'low-key' millionaire's row in Marbella, the terracotta mansion stands out for its state-of-the-art security. High-tech CCTV cameras tower above either side of its entrance gate, offering full coverage of the street below. More cameras are mounted on the villa itself, alongside lights and an alarm system to ward off would-be intruders. A high wall runs along the property's streetside perimeter, lined with towering trees, guaranteeing privacy.
