This gate to an old, uninhabited tenement house at Prozna street, brought some memories.
When I was a child, for some 3 years I was living with my parents and grandparents in a brick apartment house; on both sides of the gate there were cast iron dwarfs very similar to these on the photo.
Their destination was to prevent the sides of the gate from damage caused by the wheels of too wide cars.
Are they called buffers in English?
