text: Are there really two protected areas here? It seems the outer version was intended as a kind of buffer zone, as it carries a lower protect_class, however, the area is so small I seriously doubt there is an official government agency established buffer zone here. Also, the borders seem very coarsly drawn, even overlapping parking areas.
  Either combine these two into a single protected_area if no officially recognized buffer zone, or create a multipolygon relation and cut out the inner part from the outer if this is official.
