Alleys are lines that can be found mainly along roads. They can decorate one or both sides, but also create an accompanying element of streams and land boundaries. When planting an alley along the road, a sufficient distance from the curb must be maintained. It should be at a minimum distance of 5 to 9.5 metres so that the trees do not form an obstacle for the passage of vehicles. Unfortunately, even these reasons can limit their planting nowadays.
They have had their place in the landscape since ancient times. An example can be Hadrian's Villa in Tivoli near Rome, where trees line the path between buildings. For more than four centuries, they have been a distinctive man-made landscape feature. In the 19th century, they were even compulsorily planted around the new imperial routes. These trees create a unique landscape, which has been destroyed in recent years by felling them in reference to road safety.
Alley. The route that will lead us home safely. A belt of sounds and smells, under which we can walk endlessly. Whether composed of only one species or flowering in different colours, it is an indispensable complement to rivers and streams. It is a living boundary that accompanies all good journeys. It naturally divides the landscape and helps people find their way, whether in cities or in nature. The tradition of alleys dates back to the Baroque period, when they created a shadow for the passing troops.
