How to unforgettably spend the last days of the autumn holidays? Go on a picnic? Collect material for a school history project? By the way, you can have a picnic in the grove where seven centuries ago Romove was located, the ancient sanctuary of the Prussians, destroyed by the Teutonic knights during the Crusades, and from where people sometimes do not return. And photos for the project can be taken in an abandoned German pillbox, where behind a steel hermetic door there is a staircase leading deep down, underground, to the railway, where it is still 1945. Four Kaliningrad schoolchildren will definitely not forget such a weekend. For middle and high school age.
