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.

Artist Timothy Yufit’s In Place project uses Layers of London to document displaced headstones embedded within London’s parks and public spaces. These fragmented historical traces remain present within the contemporary urban landscape. www.layersoflondon.org/map/collecti...

More Ice Age London Outreach this Thursday 🦣🏺

I’ve added four more walks to my London Walks schedule this year. You can find them all at this link www.walks.com/guides/ruth-1/

Today's #FavouriteSite comes from @nathaliecohen.bsky.social (Archaeologist in London & the SE):🧵 "During a previous role with the Thames Discovery Programme) I was lucky enough work often on the foreshore in Chelsea - a favourite site! There are the remains of 2 early medieval fish traps here: 🐟

At Effra Quay today on the hunt for one of London’s famous lost rivers, the Effra, which once spanned the length of Lambeth, travelling from Upper Norwood through West Norwood cemetery, around Brockwell Park & Kennington Oval, before reaching the Thames at Vauxhall Bridge near the MI6 building 1/

Bexley to Bromley via Sidcup & Chislehurst #SlowWays today. Some wide suburban pavements and some narrow muddy paths. Stayed upright!Quite some variety across SE London.

We had a good day yesterday at the Essex Gem, Fossil & Mineral Show. LGP shared stands(as ever) with @geolassoc.bsky.social. London’s building stones are also part of LGP’s remit and we had a small display of Portland Stone, London’s iconic building stone. Link is in the comments for more info 1/2

A special day for LGP today! Formal inauguration of our Layers of Bermondsey sign at Chambers Wharf this morning 🧵

Looking for something to do with the kids this half term? Join us for a hands-on adventure into the world of fossils! Families can dig, discover, and create as they explore the secrets of prehistoric life together. 📆 Thursday 19 to Sunday 22 February, 10am to 4pm 🎟 £3.50 per child ✨ Drop in

LGP will have a stand at the Essex Rock & Mineral Show this Saturday (21/02/26). We will have small display of London’s geology and building stones, will be doing rock and fossil IDs and will be selling @geolassoc.bsky.social guide books. Do come and say hello!

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?

As a proud resident of Wilcumstowe, I love this marvellous map of Saxon London by Matt Brown londonist.substack.com/p/mapping-an...

#Urbangeology Christmas Quiz! Can you guess where I am in the UK from the stone below? (I know there are a few of you who will get this immediately!)

6.30pm Monday 8 Dec online What can zooarchaeology tell us about the lives of the dogs & bears involved in animal-baiting on Bankside and beyond? A catch-up link will be made available to those who have bought a ticket but can't attend on the day.

We have a hew information sign in Bermondsey! Designed and organised by our members and artists @gaildickerson.bsky.social and @deemcleanart.bsky.social and located near the Tideway excavations at Chambers Wharf, it illustrates geology and archaeology from this reach of the Thames #londongeology

I’ve written a piece on the curious lack of media and political interest in the issues faced by our national @britishlibrary.bsky.social. This is strange given we live in a world where ideas, knowledge and research are a long-term source of innovation and insight www.cityam.com/the-british-...

Why are all these chalk boulders on the foreshore of the River Thames? They are derived from barge beds - platforms constructed from chalk blocks onto which barges could beach. You can often see remains of barge beds ie at Battersea #londongeology #urbangeology #Thames

#FossilFriday at #SVP2025 today! Emma Bernard will be talking about dating the amazing @nhm-london.bsky.social chalk fish collections at 09:30 in Hall 4. Then check out posters by Twitchett/Underwood and Kaia Spence on new #chalk sharks & coelacanth size in Poster Session III, Hall 3 (4:30 - 6:30).

Unravel the curious case of the 1725 London Excursion — a field report that seems to have been written 200 years before its time. Join Nina Morgan as she pieces together clues to uncover the real story behind the publication 🕵️‍♀ geoscientist.online/sections/fea... #geoscience #geology #history

Great to be back in the wonderful Yorkshire Museum today for a day in women in geology organised by the Yorkshire Geological Society.

A wet day out to look at the Pulhamite outcrops in Battersea Park. These are man made ‘outcrops’ constructed in the 1870s #urbangeology #londongeology

Did you go to the @geolassoc.bsky.social Festival of Geology this weekend? Please do share your photos of walks, talks and other events! #festivalofgeology #fog

This was a lot of fun to write for the BBC - the joys of 'urban geology': fossil-hunting and more in the buildings of central London with @pavementgeology.bsky.social. She even showed me a possible dinosaur bone! #urbangeology www.bbc.com/future/artic...
