Salt is known today as the municipality with the lowest per capita income in Catalonia. Also one of the towns with the highest concentration of migrant population: nearly 40% of residents are of foreign nationality. But what headlines have overlooked in recent years is that almost half of this town's surface is still orchards and pastures. The Monar canal, parallel to the Ter river, marks the border between the built-up Salt and the agricultural zone. Few facilities surpass it, except for a large institute built on fertile land. Located on the border with Girona, surrounded by greenery and with magnificent views of the Mare de Déu del Mont, lies Vallvera. A secondary and vocational training center with more than 1,200 students, inaugurated in 2008, which contrasts with its surroundings by being a large gray sheet metal center with a concrete-filled courtyard. "In winter it's a refrigerator and in summer an oven, there's no in-between!", laments the director, Ferran Maimir, who started this academic year with a direction very focused on working for the renaturalization of the courtyard, but with a different method: that the students themselves build the shade with their hands.
