Corullón Castle dates from 15th century. Its tower was copied to build a similar one in Tuscany (Italy). Today, the tower and the surrounding ruins are still preserved. The best place which has been preserved is the Tower of Homage. On its entry point, two armorial bearings mark both houses, Osorio´s House and Valcarce´s House. It is a squared tower with three storeys, separated by imposts, battlements, modillions, meurtrières, and the remains of a great nave in tree sections. Its construction is from 15th century and it belonged to Alvarez Osorio until 1486, and then to Álvarez de Toledo.
Currently, the castle belongs to the Marquises of Villafranca´s descendants who restored it some years ago.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.
