Harmondsworth Barn is one of @londongeology.bsky.social’s Sites of Geological Interest (SGI). Read more at this link londongeopartnership.org.uk/wp/wp-conten...

I spent yesterday measuring blocks at the spectacular Harmondsworth Great Barn near Heathrow - a rare example of a secular medieval building in London. Famous for its (mostly original) timbers, stone is an important part of its construction and something I’m currently working on #urbangeology

Last chance approaching… 📸The London Rivers Week Photography Comp 2026 is open for entries. 🪴Showcase London’s rivers: nature, wildlife, and people enjoying blue spaces. 📷 Deadline: 1 May 📷 ow.ly/rJGo50YLhM4

As part of GeoWeek 2026 the London Geodiversity Partnership have organised a geotrail to Croham Hurst, Croydon, in conjunction with John Hines and Eleanor Redshaw of Croydon Natural History and Scientific Society. More info on our website londongeopartnership.org.uk/geotrail-to-... #londongeology

I’ll be giving a public lecture on mineral pigments in art @geolsoc.bsky.social on the evening of 21st July. You can attend in person or watch online. Registration details in the link below www.geolsoc.org.uk/events/miner...

My next #urbangeology walk with London Walks will be on 2 May 2026 and will be all about the rocks, minerals and fossils in building stones in the City of London. Reservations and more info is at www.walks.com/our-walks/ge... See you there!

Does your team need to know more about London’s geology? We lead walking tours for organisations to introduce the stratigraphy of London - crucial to urban planning and engineering works. Here we are walking in Waltham Forest with a group of TfL engineers #londongeology

Our member Di Clements will be presenting a virtual walk down the River Westbourne on 21st April at Camden Local Studies Centre. Full info in the poster and alt text below. #londongeology #riverwestbourne @camdencouncil.bsky.social

Public toilets at Maida Hill Market are clad in reclaimed and reused igneous plutonic rocks; red rapakivi granite from Finland and Norwegian larvikite. You can still see the plug marks on several blocks showing the quarrying technique. Cities need public loos! #urbangeology #reuse #reclaim #london

Beneath the street named Walbrook in the City of London is a stream of the same name. It was an important source of water for Roman London but during the medieval period was used as a sewer and had been covered over by the 17th century.

Harmondsworth Great Barn will be 600 years old this year! It is one of our London Sites of Geological lnterest. Read about it here londongeopartnership.org.uk/wp/wp-conten... #londongeology

The splendid website London Pavement Geology (www.londonpavementgeology.co.uk) has been extended across the UK and tells you where to find treasures hidden in plain sight. Here are some London fossils from the LSE and Somerset House.

Now, a study from University of East London looks at ways to restore some of the "sponginess" the city has lost, protecting vulnerable homes & businesses. share.google/2iw1I5qDkKA7...

Once, marshes in East London could absorb some flood water. We've built over these with a sea of concrete, losing the 'sponginess' to absorb intense climate-driven rain. Sewers built for an era of lower rainfall can be overwhelmed, contaminating flood waters. 🧵 1 share.google/9GzrOUZUubep...

Thanks to Ben Lerwill for a lovely article on my #urbangeology walks in today’s @theguardian.com www.theguardian.com/travel/2026/...

You can learn more about the excavation findings at the Curtain Theatre from this Museum of London Archaeology blog post: www.mola.org.uk/discoveries/... The team shares the remarkable discovery that the stage was 14 metres long (directly related to Blyth’s argument about R&J's fight choreo).

The latest edition to our Greater London Authority #geosites is Gunnersbury Park in Hounslow. The geology is mainly Langley Silt Member, Maidenhead Formation (Pleistocene-Holocene) and parts of the current park were once brick pits.

An urban geomooch around the city of London today. Paid a visit to Irongate House clad in South African Parys Gneiss with black veins of pseudotachylite - glass formed through meteorite impact - quarried in the Vredefort Structure. Extraordinary #urbangeology. See ruthsiddall.co.uk/Walks/Ironga...

We see your Humble Jumble Lane and raise you Crack-brain-court and New Martin Street a.k.a. Shall-I-go-naked-street! These are from Whitechapel, London, in the early 1700s. Does anyone have any more stupendous street names, from #OnePlaceStudies or elsewhere, to share on #OnePlaceWednesday?
