Perched at an elevation of 70 metres, Flowers Hill sits in the southern reaches of Bristol, with coordinates placing it at approximately 51.4237° N, 2.5499° W. The area occupies a naturally elevated position, and this high ground has long made it a point of geographical significance within the city. A triangulation pillar – a pillar-type survey point established by Ordnance Survey and referenced as ST57/T81 – marks the summit, linking the spot to the national network of geodetic survey stations that were used to map Great Britain with precision.
The Triangulation Station
The Flowers Hill trig point is one of thousands of such pillars placed across the United Kingdom by Ordnance Survey during the twentieth century. These concrete pillars were positioned at prominent high points to allow surveyors to take accurate sightline measurements across the country, building up the detailed maps that have been in use for decades. While modern GPS technology has largely replaced the original surveying function of these stations, the pillar at Flowers Hill remains standing and is catalogued as part of Ordnance Survey’s legacy control information. The peak designation associated with the location reflects the natural rise in terrain here, which stands noticeably above much of the surrounding suburban landscape in this part of south Bristol.
The Surrounding Area
The wider neighbourhood around Flowers Hill is a residential part of the city, situated broadly in the Brislington and Knowle area of south Bristol. The elevated ground here offers views across nearby parts of the city, and the location sits within relatively easy reach of the main arterial roads that connect south Bristol to the city centre. The Ordnance Survey trig pillar gives the spot a minor but genuine point of interest for walkers, local historians, and those with an interest in the history of British cartography. Visitors curious about the station can find further information through the Ordnance Survey’s online records of triangulation stations across the country.
