The stone church of Grundsunda was probably built in the 14th century. Arches were added later in the Middle Ages as well as the porch and sacristy. Walls and the roof were decorated with murals around 1600, but them were overpainted in the 19th century. The wooden belfry was erected in 1794. The unique font dates from the 17th century and is made of single piece of wood. The pulpit was carved by Tomas Kiempe in the 1720s.
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.
