Barcelona returned to their home stadium for the first time since their Champions League final win that saw them complete the treble last season.
The ceremony took place before Barcelona’s pre-season clash with Roma. Turan received one of the loudest cheers when his name was announced.
The Turkish international joined Barcelona on a £24 million deal from Atletico Madrid earlier this summer.
However, due to the transfer ban imposed on Barcelona by FIFA the La Liga champions cannot register new signings until the turn of the year.
Turan was unable to play any friendly games over the summer either although he was able to participate in team training.
The former Galatasaray midfielder joined Barcelona on a five-year deal and became the third Turkish international to join the La Liga champions.
Turan provided six assists and scored three goals in 46 appearances for Atletico Madrid last season.
