There is. I didn't notice the plaque but at least one person took a photo once. The text is difficult to read but one can make out the words
Xunta - "Government", with "Galicia" beneath it perhaps - and then the words
Conselleria de Agricultura, Ganaderia y Montes - "Department for Agriculture, Lifestock Farming and Mountains" - followed by "1992". The Holy Year 1993 was the year for which the regional government of Galicia had heavily promoted the
Camino de Santiago to attract Spanish and international visitors to Galicia. It is the year when the contemporary
Camino de Santiago really took off as an international destination. The fountain was presumably financed in the context of a program for rural development - hence the department for agriculture is named and not a department for culture or religion or tourism.
So there is a story to the fountain after all. More recent and more prosaic than expected perhaps but a story nevertheless.
