Newly restored back to its opulent best, 93 Palm is the former home of notorious gangster, Al Capone. Boasts a whopping 7 bedrooms, 5 baths, guests house, cabana and 60,000-gallon swimming pool, the Miami mansion is surrounded by a 7-foot security wall, though hopefully the new resident hopefully necessarily need such high security. Located in the Palm Island neighbourhood, 93 Palm is on the market for $15m through MB America: www.mbamerica.net/93palm
