Without a doubt, the centre of Vigo’s Old Town is Praza da Constitución Square, which once housed the old Town Hall (currently the Casa Galega da Cultura Cultural Centre). A meeting point for visitors and neighbours, this is the place where celebrations like the Maios or the Reconquista are held, and it’s also a daily meeting point for an afterwork drink in Vigo.
