Visit the site of one of London’s recent terrorist attacks and the new safety barriers are unmissable.

Strung across London’s central bridges, these metal and concrete buffers are a grim reminder of the recent violence here, where attackers affiliating themselves with ISIS drove into crowds before attacking passers-by with knives. There could be far worse reminders, of course—these barriers still shield pedestrians from some of the deadly possibilities of vehicular terrorism. But in a city that’s trying to return to normal, people are asking if there isn’t a better way to protect citizens, one that isn’t so stark, harsh-looking, or imposing on daily life.
