The old loading dock building on the San Miguel Bridge has been rehabilitated as an Astronomical Observatory, allowing its conservation as a significant element of industrial architecture. The aim is to take advantage of this resource to recover and transmit popular kowledge related to the stars and the sky: the best times for felling, shearing, sowing... that our ancestors faithfully preserved. Observe the universe from this magnificent viewpoint, enjoying a visit to the entrance of an authentic mine, checking the mark left by coal mining activity in this region.
