Ponte da Lima At the extreme north-west of Portugal, Viana do Castelo, the capital of the district of the same name, is a gem that combines architectural richness and a gentle way of life. It is surrounded to the north and south by the magnificent beaches of the Costa Verde. Also not to be missed are the old streets of Ponte da Lima and its magnificent original Roman bridge. So, if the pounding waves of the Atlantic don't scare you and you like vinho verde, why not invest in this part of Portugal? For the property market in the Viana do Castelo area has lots of properties for sale at all prices: apartments, plots of land, houses, farmhouses for renovation... something to suit one and all.
