ABSTRACT:
This paper presents the work done to recovey the historical Fuente Santa spring, well known at Middle Age due to its miraculous medical effects. The spring was buried by San Antonio volcano eruption in 1677, with debris, cinders and lava flows. A gallery was recently excavated under extreme and difficult natural conditions, a total lack of stability with granular materials involved. The direction of the axis of the gallery was initially unkown.
