As we learnt at the #Harmondsworth Barn 600th Anniversary Conference from Ruth Siddall @pavementgeology.bsky.social

The Great Barn at #Harmondsworth is celebrating its 600th anniversary.
The architectural jewel in the crown of the Colne Valley Regional Park, a glorious mediaeval building described by Sir John Betjeman as 'the Cathedral of #Middlesex'.

Excellent day at the #Harmondsworth Barn 600th Anniversary Conference held in St Mary’s Church on Saturday.
Many thanks to Justine Bailey, the many #volunteers from Friends of Harmondsworth Great Barn and English Heritage for organising.
