Imagine the city where only pedestrians and vehicles with no engines are circulating and moving about.
Imagine walking on streets that are covered with paintings related to the history of the city.
The air of the city would be cleaner.
The noise would come only from the pace of the passers-by, the scooters, the bicycles and the urban nature.
The history would be visually anchored in our memory as well as the ground of the city. And we could enjoy it in silence as a contemplation.
