There is a way of keeping a place that has nothing to do with holding it still. In England they call it beating the bounds.
Once a year, or every few years, a parish walks its own edge. The priest, the churchwardens, the boys. They carry green branches, birch or willow, and beat the boundary stones as they pass, and say the line out loud so it is remembered. Sometimes they bump the boys against the stones, or whip them, so the edge enters the body and stays there.
The custom is older than the maps. It reaches back before the Norman Conquest, and maybe further, to a Roman feast for Terminus, the god of boundary stones. Before maps were common, the only reliable copy of an edge was a habit of walking it.
Turnworth, in Dorset, wrote its walk into the parish register in 1747:
“On Ascension Day after morning prayer at Turnworth Church, was made a public Perambulation of the bounds of the parish ... with 4 boys; beginning at the Church Hatch and cutting a great T on the most principal parts of the bounds. Whipping the boys by way of remembrance, and stopping their cry with some half-pence.”
A boundary has no substance. You cannot put it in a room. A fence rots; a stone is lifted and set down a metre away; a map is drawn and then argued over. The only durable copy is the walk. The edge is real on the day feet return to it, and real for exactly as long as they keep coming back.
At the Tower of London, the Liberty and the parish of All Hallows-by-the-Tower have walked the same boundary, on the same day, for over seven centuries. When the two processions meet, they stage a mock confrontation, remembering a riot in 1698. Nobody owns that line. It is kept by everyone who shows up.
At Bodmin, in Cornwall, the custom went quiet. In 1865 the mayor, William Robert Hicks, brought it back. It runs about every five years now and ends in Cornish hurling: the mayor throws a silver ball into the Salting Pool, there are no teams and one route, along the old A30, Callywith Road, Castle Street, Church Square, Honey Street, to the Turret Clock in Fore Street. Whoever carries the ball to the clock gets ten pounds from the mayor.
When the walking stopped, Bodmin's bounds did not vanish behind a wall. They thinned, and the fix was simply to return.
I have spent a while on the wrong kind of keeping. A painting held in a locked room is not kept. It is only stored. This is the opposite. A place that survives precisely because strangers keep walking back to it. It cannot be saved by anyone who tries to hold it still.
