It’s a naturalistic oasis that includes an area of 35 square feet between San Floreano Hill and the provincial roads of San Daniele-Fagagna and Majano-Fagagna. It is characterized by presence of naturalistic heritage of great interest which are at risk of extinction or destruction with related protection rules. This delimited space contribute to the maintenance of biodiversity in the regional territory thanks to the presence of botanical species included in the Red List.

The ancient village is situated to the south of the castle of Arcano, with a view of the Ledra canal and the Corno valley. According to several sources, its origin is thought to date back to a period somewhere between the 15th and the 16th centuries. A fief of the nobles of Asquino, the village cultivated the farmsteads, the products of which constituted the prebends of the Chapter of Aquileia. The small settlement developed over time from rural buildings, which can be accessed via the typical hallways of the farm buildings. The characteristics of the dwellings is the distribution of their rooms, which is only slightly different between one building and the next: on the ground floor there are cellars and stables, while on the first floor there are the bedrooms and in the attic the hay barn; to the rear, the barnyard and the vegetable gardener divided among the different families. A central element of the rural settlement is the little church of San Giorgio, slightly raised with respect to the clearing in front of it. The building was consecrated in 1505 and consist of a main hall, preceded by an entrance hallway with a roof supported by two pillars; on the top of the building there is a small double lancet bell tower in which there are two little bells. Next to the church, there is an ancient rural building, recently renovated, with stone walls and the remains of several pointed windows made from bricks.

Placed on an elevated moraine terrace engraved by the confluent Petoc torrent and Corno valleys, in a favorable position with respect to the plain bowl. The Castelliere of Rive d’Arcano called “della Zucule” ( inner surface of 3,6 square meters and a perimeter of 840 meters) it’s an extraordinary testimony of the first human settlements in the territory during the Bronze Age and the first three phases of the subsequent Iron Age. On the Northen side, not defended by the steep slope of the land, an artificial agger was erected 5 meters high and 160 meters long near which shards and bronze objects were found. 
In the 1977, the section of Prehistoric Studies of the Center of South Adriatic Antiquies has conducted some excavations on site that confirmed human presence in prehistoric age. Among the pebbles, mixed with black earth, fragments of ceramic and vases were found. The characteristics of this ceramic suggest the possibility that the Castelliere of Rive d’Arcano is framed in the late phase of the Bronze Age, an era when settlements on naturally fortified hills were far from rare. Ludovico Quarina, who was the first person to survey the castellieri and tumulus tombs in Friuli, places these artifacts believed to belong to the Euganean people, between the end of Bronze Age and the first phase of Iron Age (cent. IX-VIII a.C.).
The Castelliere area is also frequented by later populations, until the fourth century as documented by the considerable quantity of terracotta shards found mainly outside the defensive agger. In the same area substantial leftover from the forge work were collected, in particular the remains of iron ore which attest the presence of a workshop for the production of metal weapons and tools.

The Parish Church of San Martino Vescono has undergone numerous renovations and extensions over time. The Plebem des Ripis is mentioned in a bull issued by the patriarch Gottifredo, according to which in 1184 the church was donated to Liuptrando, king of the Longobards. The first structures of the church probably date back to this period. The church’s appearance is is of the eighteenth century, the same period in which the bell tower was built. The church has a rectangular main hall and a polygonal apse with a ribbed vault. Inside there is an eighteenth-century main altar (1717) with statues of the Annunciation, the altar of the Rosary (1845), the work of Pietro Fantoni di Gemona, a baptismal font delated 1541, created during the rule of the priest Zaccaria, and a Holy water font of 1504 by Giovanni Antonio Pilacorte.
Particularly interesting is the altar in painted stone, created in 1530 by Carlo da Carona with statues of saints, the Annunciation and the Eternal Father.
