About
"A globe-trotting history nerd's treasure hunt diary"
Host Josh Gates travels the globe chasing historical mysteries: lost cities, sunken ships, vanished explorers, and legendary treasures. Each episode follows him meeting local experts, digging through archives, and getting hands-on at dig sites or dive locations to test a specific theory. The tone is breezy and enthusiastic rather than academic, with Gates's wisecracking commentary keeping things light even when the research gets dense. It is comfort viewing for curious minds: satisfying travelogue footage, tidy historical puzzles, and a host who treats every stop like the coolest thing he has ever seen.
Watch it for
the infectious curiosity Josh Gates brings to obscure historical puzzles most people have never heard of.
Maybe skip if
you want hard scientific rigor rather than an enthusiastic amateur's guided tour.
