For more than seven centuries the city of Königsberg cultivated its defensive power through the construction of bastions, ravelins, towers, fortress gates, defensive barracks and a ring of bastilles. To this day these buildings constitute the core of the city. It was in the 20th century that Königsberg received a new name — Kaliningrad — and the city’s magnificent examples of ancient fortification were transformed into monuments of fortification art and military engineering thought from the second half of the 19th century. Host Nadezhda Lebedeva visited modern-day Kaliningrad to check out these historic constructions for herself in this RTG film.
