Montjuïc Mountain isn't very high, measuring just 177 meters, but it has a long history and an umbilical cord with Barcelona. Most of the city's most emblematic buildings have been built with Montjuïc stone: the Roman wall, the Roman temple, the first Christian church, the Romanesque and Gothic cathedral, the Gothic palaces of the Ribera... The discovery of the remains of a quarry face from the Great Period, meters long and five meters high (seven, if you count the two hidden underground) can reveal many things about how it was exploited. It is the oldest documented Roman quarry in Barcelona and one of the oldest in Europe, and a section will be preserved: about eight meters that will form part of the parking lot for some apartments being built on Avinguda de los Ferrocarrils Catalans, between numbers 11 and 19. However, only residents and restoration technicians will be able to see it.
