My well trained family send me photos of paving stones when they are on holiday. These are in Venice... I reckon bricks, what do you think? #urbangeology #buildingstone #paving

A visit to the Jordans/Bowers #PortlandStone Mine for the @stone-work.bsky.social team. We had a fantastic tour from #AlbionStone. An incredible opportunity to see these exposed faces of pristine Portland Formation - Britain’s global heritage stone #buildingstone #ghs #isleofportland
A view of us, wearing high vis jackets, walking through the stone mine. The tunnels are more or less square in section and recede into the distance Block is also stored in the mine until it is needed. One of our team is standing between two fresh cut blocks which are taller than her. A close up of a rare facies of Portland stone - oyster and Solenopora patch reefs occur in the Portland stones and are only revealed by quarrying. A close up of Bowers Roach - a facies of Portland Stone with distinctive and characteristic casts and moulds of fossils, including the spire-shaped gastropod Aptyxiella portlandica shown here.

Burwell Rock (a Late Cretaceous limestone) pressed into service to make a 'clunch' window frame at Great Ellingham church, Norfolk - beginning to show its age after 700 years.

It is not just voting either...
Just because you have a free vote you don't necessarily have democracy even if it's one buildingstone.
If it becomes the exploitation of the minorities by the majority, you don't have democracy, you have dictatorship of the majority.
Democracy work to better for all!
