There is some but its extremely rare. In Germany you for example have the Hambacher Forst, where parts are as old as 700 years. Its scale is however lacking

Generally you have "untouched" as in oldgrowth/primary forest and not being a secondary forest, which takes a few hundred years.

Sorry, I thought you were providing your definition of natural forest
