Talking about the Basque Country is talking about green colors, mountains and brown stone houses, called caserios where they raise livestock. What we can never imagine is that, a fortified tower house, where nobles safeguarded their lands, hides one of the five best collections of old cars in the world, including 45 Rolls Royce. All and each of them with some very interesting stories behind them. Like the Phantom IV the most exclusive Rolls Royce model ever built. Only eighteen were made between 1950 and 1956, seventeen of which were sold - exclusively to royalty and heads of state.
