Thousands of people pass St John the Baptist, Greenhill every week, yet it is easy to overlook how much of Harrow’s history is contained within its stone walls.
Standing prominently at the junction of Station Road and Sheepcote Road, the church reflects Greenhill’s transformation from a small Middlesex settlement into the busy and extraordinarily diverse centre of modern Harrow. (photos: Husain Akhtar)
The first church on the site was built in 1866, designed by Victorian architect Enoch Bassett Keeling as a chapel of ease to the ancient St Mary’s Church on Harrow Hill. Greenhill then had a population of only around 400. But the railway and suburban development transformed the area. By 1902 its population had grown to nearly 4,900 and the original church was no longer adequate.
The present church was begun in 1904, to designs by John Samuel Alder, with the nave consecrated the following year. Further work followed in 1925, and the building was finally completed in 1938 with a chancel and chapel designed by noted church architect Martin Travers.
The result is an impressive stone church principally in the Gothic Revival tradition, combining Decorated and Perpendicular Gothic influences. Its pointed arches, tracery, stained glass, substantial nave and timber roof give the building an architectural presence easily missed by those hurrying through the town centre. Its quality and historic importance were formally recognised when it became a Grade II listed building in 1994. Five stained-glass windows from the original 1866 church also survive, providing a physical connection with Victorian Greenhill.
But perhaps the most fascinating history is the story of its changing church community. In 1957, St John’s electoral roll reached its peak of 1,369 members. By 2026, it stood at just 103 — a striking 92.5% reduction from the 1957 peak.
That dramatic change has taken place as Harrow itself has undergone profound demographic, cultural and religious transformation. The surroundings have changed too. Greenhill has evolved from a largely residential suburb into Harrow’s metropolitan town centre. St John’s has adapted accordingly, recognising a wider ministry that reaches beyond its congregation to town-centre workers, shoppers, people of other faiths and those of no religious affiliation.
Yet the church has continued to adapt. It has supported community activities, Harrow Foodbank and a long-running programme of lunchtime concerts, while new facilities were added as recently as 2024–25.
That is what makes St John the Baptist particularly interesting as Harrow’s living heritage. It is not simply an old building to be preserved. Its Victorian origins, Edwardian rebuilding, twentieth-century congregation and place within today’s multicultural Harrow tell, in one location, something of the remarkable story of how the borough itself has changed.
