A field on Princess Road, and the 1870 Act

Before the school there was farmland. The ground on Princess Road where Primrose Hill Primary now stands was a field where horses were kept — one of the last agricultural fragments in a district that the Chalcot estate builders were rapidly covering with terraces.

What changed the use of that field was national legislation. The Elementary Education Act of 1870 established that where existing voluntary and church provision was inadequate, elected school boards could build schools out of the rates; attendance became compulsory for children from five to thirteen. Primrose Hill, filling with working families along the railway and the canal, plainly qualified. Building on the Princess Road site began in 1885, the work took about a year, and Princess Road Board School opened on 9 February 1886.

Nine hundred children, and the Smut School

The scale of that opening is the detail most people find hard to credit. Around 900 children were on the roll — a figure that reflects both the density of the surrounding streets and the way board schools were designed, stacked vertically with separate departments for boys, girls and infants and very large classes by any modern measure.

A Victorian observer quoted in the school's own history described the pupils as "without exception well-clad… generally hearty, healthy-looking, full of spirit", which is a more cheerful verdict than the surveys of the period often returned for inner London. The local nickname was less flattering and more accurate about the setting: the school was known as the Smut School, because by the end of the day the children's clothes had picked up soot from the steam engines passing on the lines below Primrose Hill. It is a reminder that the modern picture of the district — quiet, expensive, residential — is a recent one. In 1886 this was a railway neighbourhood, and the school stood in its smoke.

Evacuation, and the arches under the school

The building has now stood through both world wars. In 1939 most of the children were evacuated to Fleetville School, at St Albans in Hertfordshire, where they remained until 1945. The head teacher, Mr Clayton, recorded the parting from the host community in terms that have survived in the school's records: "We leave St Albans with regret, but the friends we have made… will always be a link."

For those who stayed or returned, the school itself became shelter. During the air raids of the 1940s the arches beneath the building were used to protect children from the bombing. That combination — a school partly emptied by evacuation, partly functioning as a refuge — was the ordinary experience of London elementary schools in the war, but it is unusual to have it recorded so specifically for one building.

Coalport steel, glass partitions and parquet

What makes Primrose Hill Primary worth writing about architecturally is how much of 1886 is still in use. The school's own account of its fabric lists the surviving Victorian elements: glass partitions between teaching spaces, steel beams brought from Coalport in Shropshire, green and brown tiling on the staircases, and parquet flooring. These were not decorative choices so much as the standard technology of late-nineteenth-century school building — fireproof structure, hard wearing surfaces, and glazed screens that allowed a head teacher to see into more than one room at a time.

The result is a building whose plan still tells you how Victorian elementary education worked, while accommodating a curriculum and class sizes it was never designed for. The continuity is not merely structural. A former pupil aged ninety-eight returned to visit and recognised the classrooms she had sat in decades earlier — a span that reaches back towards the school's first fifty years.

The same rooms, a different neighbourhood

Almost everything around the school has changed since 1886. The steam locomotives that gave it its nickname have gone. The terraced streets that supplied 900 children now hold a fraction of that number of school-age residents, and the district's demographic profile has been transformed twice over — first by wartime damage and post-war rebuilding, then by the arrival from the 1990s of the professional and media households that gave Primrose Hill its later reputation.

The school has absorbed all of it. It sits within the Primrose Hill Conservation Area, designated on 1 October 1971, so the Victorian exterior that generations of children have walked past is protected in the same way as the terraces around it. Records of Princess Road School are held in the public archives under that original name, which is the cleanest indication of how far the institution predates the district's current identity.

Board schools were built to be permanent civic statements, and comparatively few of them have kept doing the job continuously for well over a century on their original site. That is the real interest of Primrose Hill Primary: not a single dramatic episode, but the fact that a building put up in a horse field in 1885 has taught the children of this small NW1 district through the age of steam, two wars, and the neighbourhood's complete social reinvention, without ever moving.
