Whith the expert in organ conservation and restoration, Óscar Laguna, one of the members of the team who worked on the recovery of organs such as those of the University Church, San Paio or Iria Flavia, we will take a look back at the fruits of the restoration work undertaken in recent decades in our city. We will talk with him to learn about the details of his work, to find out what it is like before and after a restoration and to make an assessment in the light of the results of these projects decades later.
