Kaliningrad, or Königsberg— the mysterious Baltic city shrouded in fog in the west of Russia. For centuries, the ancient residence of the Teutonic Order knights was an arena for rivalry among many powers: the Polish-Lithuanian Commonwealth, Prussia, and Russia. In the 19th century, the home of Kant became Napoleon’s last refuge after he fled from Russia. The city’s turbulent and complex history, the lives of ordinary townspeople, music, ancient superstitions, and legends—everything is covered in a new book in the series “A History of the City in Your Hands.”
