Pushy mothers

Weird experiments in stone and glass clutter the South Bank opposite the Tower of London. The near-spherical City Hall looks like a speeding squash ball photographed at the moment of impact with a racquet. Around it stretches an acre of sloping flagstones, ideal for freestyle biking and skateboarding. (Sure enough, both activities are vigorously suppressed by patrols of scowling guards.) Nearby, the Scoop is a roofless amphitheatre fashioned from a crater of layered granite. It’s an eerie and compelling sight, as if a divine whirlwind had ripped deep spirals out of a barren moonscape to produce a huge grooved funnel. As I took my place on a freezing seat, I sensed that the artificiality of the space seems to work against the warmth and intimacy it’s supposed to generate.

 The theatre hosts free performances of Brecht’s The Mother until 4 September. This 1932 drama sketches out life in Russia during the 15 years leading up to the revolution.
