19. Castle And Principal Garden, Konigsberg, East Prussia, Germany

Built In 1255 And Demolished In 1968
The heart of East Prussia, this castle endured World War II bombings but retained its walls. It represented centuries of regional history.
Post-war Soviet control led to its systematic demolition by 1968. The unfinished “House of Soviets” replacement was itself razed in 2024, underscoring the site’s turbulent fate.
