So-called Jätinkirkko (“the giant’s church”) of Kastelli is a rectangular stone rampart measuring 36 x 62 meters. It dates back to the Stone Age and is one of the most significant ancient structures in Finland. The fort was probably built between 2700-2200 B.C like most of the stone constructions in northern Botnia.
The structure is located at top of the hill. The rampart, which is two meters high in its present state, has six gateways. In the environs are more than twenty rock cairns, a representative group of ten trapping holes and a stone age dwelling site lower on the slope.
Kastelli represents the earliest monumental construction in Finland in a form which is rarely found in hunter-catherer cultures. National Board of Antiques has submitted Kastelli site to the UNESCO Tentative List of World Heritage Sites.
Manarola is a small town, a frazione of the comune of Riomaggiore. It is the second-smallest of the famous Cinque Terre towns frequented by tourists, with a population of 353.
Manarola may be the oldest of the towns in the Cinque Terre, with the cornerstone of the church, San Lorenzo, dating from 1338. The local dialect is Manarolese, which is marginally different from the dialects in the nearby area. The name 'Manarola' is probably a dialectical evolution of the Latin, 'magna rota'. In the Manarolese dialect this was changed to 'magna roea' which means 'large wheel', in reference to the mill wheel in the town.
Manarola's primary industries have traditionally been fishing and wine-making. The local wine, called Sciacchetrà, is especially renowned; references from Roman writings mention the high quality of the wine produced in the region.
