Reto Roman

Language spoken in the Graubünden (or Grischu - as its called in Rumantsch) canton of Switzerland.

Only about 1 percent of the Swiss population - 70,000 people - are left on this planet to speak the language that is considered to be one of the oldest ones still existing, as it is extremely similar to the Latin spoken in ancient Rome.

Actually, the language is also very similar to Italian, at least in its written form.
