The Iron Road of La Fregeneda Curiosity · La Fregeneda, Vitigudino, Salamanca Image of La Fregeneda, not of the place itself. To cross Las Arribes, the railway stretch between La Fregeneda and Barca de Alba needed twenty tunnels and a dozen bridges excavated and laid over the precipice. The line was opened in 1887 and closed in 1985; today it is walked on foot. Photo: Tanja Freibott (CC BY-SA 4.0) What to see and do in La Fregeneda
