METRO  The first metro line was launched in Barcelona in 1924. The network was growing intensely with the city expansion and later stimulated by disappearance of the tram. Nowadays the metropolitan of Barcelona has 12 lines with nearly 130 km of rail lines. Metro proved itself as one of the most efficient way of transportation in the city of Barcelona with more than 300 M passengers a year.  The yellow L4 line of metro going through the site underground was opened in stages. In 1976 Barceloneta station started to be used, in 1977 the next part of the metro was opened. On combined aerial views from 1992 and 1974 position of the un- derground tunnel can be seen precisely.  Open method construction was used to develop part of the metro network located on the analyzed site. It resulted in rather low depth of location which should be considered when developing an architectural intervention proposal for the area.
