In the chapters above mostly pessimistic estimations are given as the chances of concrete finds or discoveries. In general terms, the most famous stories are good for authors but not for searchers.
However, even among the classic history mysteries there are a few threads that must not be dismissed at this time. Indeed, I consider them interesting enough not to talk about them in detail today. The basic stories themselves are well known to searchers so a few hints will not give away too much.
One is a list of antique treasures and their hiding places. The list I am sure is authentic. Among other problems the place descriptions are so vague and use unidentified place names etc. that until now not a single location was found, not even empty.
Another one is a terrible event described by an antique historian who is considered reliable. To date, modern historians are not sure this event really took place. If it was real it left behind a large number of relics in a remote place. In the last 150 years those who travelled the area looked out for evidence and found nothing that could be surely attributed to the event. In view of the size of the area in question that does not say much. Today, the government of this country requires a special permit just to get there.
There are a few more search projects with respect to world history that justify more research and possible search trips. Trips that, if successful and published, have enough substance to make their way into the National Geographic magazine. But these projects are not located in Central Europe and require more funds than I am willing to spend at the moment.
To conclude this section I have to stress, though, that in my opinion the chances to find something unusual, maybe even spectacular, are better if the searcher stays away from the famous riddles, relics and treasures and instead goes for the little and not so famous ones. I am sure there is still plenty to be found.
