The Barbican Interior — SÉRIF

On Britain's largest brutalist estate as cultural institution — and what it offers the visitor who arrives without a plan

The Barbican Centre is not difficult to enter. It is difficult to understand — which, in a city that usually delivers its institutions with clear signage and confident extraction, is a quality worth seeking out.

The Barbican Centre is not difficult to enter. It is difficult to understand — which, in a city that usually delivers its institutions with clear signage and confident extraction, is a quality worth seeking out. The estate was designed to be internally complex, its raised walkways looping above street level, its residential towers marking orientation without clarifying it. This is not a failure of wayfinding. It is a decision about what the interior of a city should feel like.

The architecture is Chamberlin, Powell and Bon, 1969–1982 — New Brutalism in its civic rather than intimidating register. The concrete is board-formed, the planting is generous, the lake at the estate's centre is large enough to reflect the towers and calm enough, on quiet mornings, to hold birds. The building has been consistently misunderstood, celebrated, resented, and gradually revalued over its half-century in London. It is now broadly accepted as one of the most considered urban environments the city built in the twentieth century.

The cultural centre that anchors the complex runs a programme of consistent seriousness: music, film, theatre, visual art, design. The Barbican Cinema screens repertory and contemporary work without the programmatic anxiety of institutions that must attract everyone. The galleries have held significant exhibitions without requiring the queue that larger institutions demand. The LSO is resident here.

What the Barbican offers the visitor who arrives without a plan is something rarer: the experience of a building that has its own internal weather. On a grey afternoon the high walkways collect ambient sound differently from the street below. The concrete changes temperature slowly. The lake holds its light after the sky has shifted. This is the particular gift of large, seriously considered architecture: the building produces conditions rather than merely enclosing space.
