Since our territory is rich in calcareous stones, there are many remains of kilns used for the baking of lime. These are simple and primitive buildings, made of an underground dry-stone wall in the shape of a cylinder with a tunnel at the base to stoke the fire. Inside the kiln, with carefully chosen stones, a sufficiently large dome was built to let the fire burn freely. The spare stones were placed above. The baking went on uninterrupted for many days and it was necessary to have a large quantity of fuel, usually faggots and branches, mainly what was left behind from logging. The lime (quicklime) was then sold and transported in clods. To use it, it was necessary to extinguish it with water. By doing this, the lime heats up and reaches a temperature of 300 degrees. The slaked lime could be stored for decades in holes. Mixed with sand, it was used as binding material in building works. It was also used for floors or to build partition walls, to whitewash and plaster, to disinfect vegetable gardens, hen-houses, and stables and to fight pests.
In the nineteenth century the production of lime was put up for auction by the patriciate. Remains of other kilns can be seen in Curölgia, and along the footpaths that go from Múrio to Cioásc and to Sass Gránde (Denti della Vecchia). The best-maintained kilns can be found in the wood on the "Monti di Cóla", in the territory of Villa Luganese.

The Luganese Regional Bus Line covers the Lugano – Sonvico stretch; from Val Colla you can reach Sonvico, using the postal bus from Tesserete to Sonvico.
The comparison between past and present, at every step of the way, will make us more aware of the delicate and complex relationship between living organisms and the surrounding nature.
No community survives without water. Therefore, it is not a surprise that the village centre of Sonvico developed around a well and a stream.
Located in the main square, it was the administration and justice building of the Castellany of Sonvico, which included the villages of Sonvico, Dino, Villa and Cimadera, Tració.
Chestnuts ensured the food subsistence for the population even during the winter. Amongst the many ways of preserving this precious fruit for an extended time, is the desiccation of the chestnuts in the graad.
Milk was another essential product of our villages. To exploit all the milk's potentials it was necessary to be able to preserve it for a long time and to transform it into cream, butter, ricotta, and other cheeses.
As we leave this area south of the village centre, characterized by areas of extensive cultivation, we enter the mixed broadleaf woods.
The structure of this natural wood consists of four layers of vegetation.

This area, called Murín (mill), was characterized by the presence of three mills, one of them operated by a turbine water wheel.
We are now in a very different environment from the one in the wood we just visited: the glade.
The movement and the mass of the torrent's water are variable and considerably influence the stability of these biotopes, continuously modifying their aspect and ecology.
This building more than any other makes us think about the rapid changes that took place in the way of life during the last decades. The transition from the washhouse to the washing machine represented a very important step in the improvement in the quality of life for women.
As we leave the path that runs along the Franscinone we reach another path and here we notice a change in vegetation. The Beech appears here, a tree that does not tolerate the highly humid ground of the bottom of the valley.
The Franscinone valley is a good example of a "valley formed by erosion" and from here we have a good view over the gorge hollowed out by the torrent.
This part of the path goes along the old water duct belonging to the Utility producing electricity for the population of Massagno, which became self-sufficient in the production of energy in 1925.
The flood-level wood is typical of these periodically flooded areas along watercourses with the humid, more or less swampy areas, that provide a high degree of instability to this kind of biotope.
The small building along the path is a typical construction used for the processing of milk: a cassinél built over a water source with a chimney on the first floor.
Some of the shrubs commonly found in broad-leaf forests are also typical of shrub areas and hedges in rural areas, where the forest interchanges with meadows and fields.
Walking towards the humid area, we see a tall plantation of Copper Beech.
Walking in the woods we come across many oval open spaces. These are man-made for the production of charcoal. This activity was still in use up to World War II and later swiftly abandoned.
The whole territory is marked by the presence of man. Tilling the ground to gain pastures and meadows, and terracing were jobs that generated enough work for whole generations for many years. This demanded a level of physical effort that can hardly be imagined today.
This is an important thoroughfare for reaching the Val Colla and Cimadera (until 1878 part of Sonvico) and carries on towards the Val Cavargna. The road connection dates back to the beginning of the twentieth century.
At this stop we can observe a plantation of chestnuts that is still as it was run in the past. In the chestnut woods the trees are panted at a good distance from each other.
Leaving the chestnut woods (the result of human intervention on the vegetation), we enter a more natural and because of its beauty a more fascinating wood: the beechwood.
This is considered to be a natural monument. This chestnut is probably the oldest living piece of vegetation on our territory.
From this panoramic point, from where we can admire the hills and the mountains of the whole area of Luganese. A sight of particular beauty are the Denti della Vecchia.
This is considered to be a natural monument. This chestnut is probably the oldest living piece of vegetation on our territory.
The oratory of St. Martino has always been considered one of the oldest Roman churches of our region.
The centre of Sonvico is the most significant evidence of man's millennial presence on our territory.
This is one of the biggest and oldest Piemontese lever presses in Ticino.
The Parish church of Saint John the Baptist, mentioned already in 1375, is a monument of particular value, the result of a slow and long evolution.
