Also great is The Fall of Civilizations' episode about Tenochtitlan [1].
The podcast is the work of a British historian named Paul M. M. Cooper, who's also published a book derived from the podcast. Each episode is really well researched, incorporating recent discoveries rather than uncritically repeating old tropes. No filler, no theatrics, just really well-told history, backed by real sources.
Another excellent history podcast is The Rest is History [2], who also devoted an excellent (albeit much shorter) episode to the same topic.
