The castle complex on an approximately triangular plateau measuring 50 by 30 meters probably consisted of a defensive and residential tower , the gate tower and a surrounding wall with battlements , further protected by two section trenches that were approx. 5 meters wide and 2 meters deep. The actual castle ruin has the dimensions of 20 to 25 meters. To the east, the complex was protected by a partially natural 20 to 25 meters wide and 5 to 6 meters deep neck ditch with a drawbridge.
References: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.
