What if one of the world’s most beautiful cities isn’t what we’ve been told it is? We travel to Melbourne, Australia, where massive cathedrals, palaces, train stations, government buildings, hidden catacombs, underground chambers, and impossible architecture stand within walking distance of one another. The deeper we look, the stranger the story becomes. How were these masterpieces supposedly designed 10,500 miles away? Why do so many of these structures appear far older than the timelines attached to them? And what exactly is hiding beneath the city streets? This is a journey into one of the most mysterious cities on Earth, where every answer seems to uncover an even bigger question. Are we looking at the remains of a forgotten world? Watch and decide for yourself.
