In Pyrenean Catalan, “cóm” is a feeding trough and, in fact, this spring was often used by the horses of the village and muleteers who passed by such as the ‘arrieros’. The road where the spring is located, carrer Doctor Palau, was formerly called the Carrer dels Cavallers [knight’s street].
It was so called because this street was the main road from Seu d'Urgell to Andorra la Vella, and passed through the village and was therefore a compulsory stopping place for all ‘arrieros’ or muleteers coming through with their animals, normally mules.
