The palace, which sits on an estate 39 times the size of Monaco, boasts a wealth of amenities, from a stunning pool, "aqua-disco" and underground ice rink, to a louche lap-dancing lounge, ornate theatre, enormous entertainment complex (pictured), helipad and Byzantine-style church. Ownership of the property has been claimed by Putin's childhood friend and erstwhile judo partner, the billionaire oligarch Arkady Rotenberg, though critics dispute this.
