Uxbridge Rock Show ---> Harrow Rock Show
Due to the relocation of Uxbridge Library to smaller premises, this year's Uxbridge Rock Show cannot go ahead. The new library does not have an exhibition space that could host our Rock Show and we are looking for alternative venues.
All is not lost! The 2025 Harrow Rock Show is already planned for Headstone Manor Museum from October - December. More details coming soon!
In the meantime, don't forget about our Rock Show Online, below.

STANMORE GRAVEL PROJECT
We have exposed a section of gravel on Harrow Weald Common which is currently open, so do go and take a look. The 258 bus stops nearby and it's a wonderful location for its view over London and woodland walks. See the Project page for more details
