But these visitors aren't gathering for a tour; instead they're waiting to take part in a memorial mass
, honoring the victims of a deadly terror attack just a mile away, on the bustling Las Ramblas promenade
, the beating heart of a city now in mourning.
Thirteen people were killed
and more than 100 injured when a terror suspect mowed down passers-by in the street early Thursday evening.
A woman at the front of the queue cools herself off with a black lace fan. Beside her, a man in a crisp white shirt and fedora peers up at a statue of Jesus on the cross.
"This is something we've both wanted to see for a long time," says Meera Andrews, who is visiting the city on holiday from Wellington, New Zealand. The couple had planned to attend the 9 o'clock mass, then realized regular services had been canceled for the memorial.
