Residents and visitors are invited to explore the ancient heritage of Bromley’s Millennium Rocks through a self‑guided walk featuring the 19 Millennium Rocks located across the borough.
Families, walking groups or curious explorers are invited to walk between Bromley’s Millennium Rocks, which were installed in 2000 to mark the new millennium. These Lewisian Gneiss boulders are among the oldest rocks in Britain, having been sourced from Lochinver in northwest Scotland and gifted by The Highland Council.
A downloadable map is now available to guide walkers between the locations of the Millennium Rocks found throughout the borough’s parks and public spaces, with printed copies available free of charge from local libraries.
To celebrate the Millennium Rocks, family‑friendly rock painting activities have also been organised during the May half term, offering children and families a creative way to engage with Bromley’s geological story:
- Tuesday 26 May, 10:00am to 11:00am – Orpington Library
- Tuesday 26 May, 2:15 to 3:15pm – Bromley Central Library
- Tuesday 26 May and Thursday 28 May 2:30pm at Hayes Library
Hayes Library is also hosting a geology and archaeology session with local historian John Keefe at Family Chatty Tuesdays on 26 May at 11am and a special Lego club on Saturday 30 May at 2:15pm with the chance to build caves, stone circles and fossils.
The Millennium Rocks project was originally developed by the Ravensbourne Geological Society with support from Bromley council. Alongside the installation of the boulders, 50,000 rock samples were distributed to local school children, linking education, science and place.
