Bevis Marks, London

Walk into Bevis Marks Synagogue on a Sabbath evening and the light comes, at least in part, from the same fixtures the congregation lit in 1701: hanging brass chandeliers, candles set in them, throwing a warm and slightly uneven glow across wooden benches worn smooth by three centuries of use. The reader's platform stands toward the west end, facing the ark at the east wall, in the Sephardi arrangement the congregation's founders carried with them from the Iberian world their grandparents had fled. Nothing about the room asks to be admired as a museum piece. It has simply gone on being used, by the same kind of congregation, in the same way, since it opened.

A building that follows an expulsion

The building only makes sense against what came before it. Jews had been expelled from England by royal edict in 1290 and were absent, at least openly, for the better part of four hundred years. Their return began not with a single dramatic reversal but with an informal, administratively untidy process in the 1650s, associated with Oliver Cromwell's government and the petitioning of the Amsterdam rabbi Menasseh ben Israel, after which a small community of Sephardi Jews - many with roots in Spain and Portugal by way of Amsterdam - began worshipping openly in London. Their first synagogue, on Creechurch Lane, opened in 1657: modest, converted from an existing building, and the first in England since the expulsion. Bevis Marks was what that small, cautious beginning grew into once the congregation could afford, and dared, to build something permanent.

The new synagogue was consecrated in 1701, built on land just off Bevis Marks street in the City of London for the Spanish and Portuguese Jews' Congregation. Its builder was Joseph Avis, a Quaker - a detail the congregation has long taken quiet pride in, since Quakers were themselves a persecuted minority in the period, worshipping without the protections of the established church. The building he raised has stood on the same site, serving the same congregation, ever since. It is the oldest synagogue in the United Kingdom still in continuous use, and it holds Grade I listed status, the highest level of protection given to a building in England for its historical and architectural interest.

What the unaltered room proves

A synagogue interior that has not needed rebuilding for three centuries is itself a kind of evidence, in the same register as an inscription or a seal. It shows a community that arrived with enough confidence, and enough resource, to build for permanence rather than for a generation - and a congregation whose worship, seating arrangement, and liturgical furniture have not required replacement since. The candle-lit chandeliers are not a revival or a reconstruction; they are the fixtures the congregation has kept using. The benches are not reproductions of eighteenth-century benches; they are eighteenth-century benches. Continuity here is not a claim made in a caption. It is a claim you can sit on.

That continuity survived events that damaged much of the City of London around it. In April 1993 an IRA bomb detonated nearby on Bishopsgate, and the blast blew out windows and caused damage to the synagogue; the building was repaired and restored to use. The episode is a reminder that "unaltered since 1701" describes the fittings and the fabric people chose to keep, not a building somehow immune to the twentieth century - the congregation has repaired Bevis Marks when it needed repairing, and returned it, each time, to the same design.

Set beside the rest of the tribe's evidence trail, Bevis Marks occupies an unusual place. It is not a ruin recovered from the ground and reconstructed in argument, the way an ostracon or a seal impression is. It is a building that never stopped being used for the purpose it was built for, by descendants - institutionally if not always by blood - of the people who built it. The proof it offers is not that something happened once, long ago, and left a trace. It is that something has been going on, without interruption, in the same room, since 1701.
