Barcelona has become the first large Spanish city to announce a ban on the wearing of full Islamic face-veils in some public spaces.
The ban was designed to include any head-wear that hindered identification, officials said.
At least two towns in Catalonia, the region that includes Barcelona, have already announced bans.
Belgium and France have both recently taken steps towards restricting the use of full veils in public.
Barcelona's city council said the ban would be largely symbolic, since it was uncommon to see women in the city wearing the full veil.
"Barcelona will forbid the use of the burqa, niqab and any other item which hinders personal identification in any of the city's public installations," a council statement said.
The ban would cover public spaces such as municipal offices, public markets and libraries - but not the streets.
The mayor of Barcelona, Jordi Hereu, said the measure was aimed purely at ensuring people could be identified, and would therefore include balaclavas, motorbike helmets and ski masks.
"In no way does it target religious belief," he said.
I FEAR IT'S TOO LITTLE TOO LATE, BUT IT DOES SHOW THEY'RE WAKING UP.
