A Millennium of London’s Building Materials

Discover the fascinating history and geology of London’s building stones. London is built on clay, and although this is good for brick-making, there are no local stones of sufficient quality to build monumental and civic buildings fitting of a capital city. During Roman and Medieval times, Ragstone and Reigate Stone were imported from Kent, and following the Great Fire in the 17th Century, Portland Stone became London¹s Iconic building stone and today stone is imported from all over the world. This walk will look at the City of London’s architectural history through its building stones. No previous knowledge of either geology or architecture is necessary.

If you can’t make one of the regularly scheduled, just-turn-up, public Urban Geology walks do think about booking one as a private tour. If you go private you can have an Urban Geology Walk – or any other London Walk – on a day and at a time that suits your convenience (depending on Ruth’s and her team of geologists’ availability of course). We’ll tailor it to your requirements. And – always with private London Walks and tours – we go to great lengths to make sure the guide-walker(s) “fit” is well-nigh perfect. Ring Fiona or Noel or Mary on 020 7624 3978 or email us at privatewalks@walks.com and we’ll set it up and make it happen for you. A private London Walk – they’re good value for an individual or couple and sensational value for a group – makes an ideal group or educational or birthday party or office (team-building) or club outing. Or indeed a fab present – be it a birthday or anniversary or get-to-know-your-new neighbourhood gift or Christmas present or whatever. Merchandise schmerchandise (gift wrapped or not) – but giving someone an experience, now that’s special. Memories make us rich.


It all comes down to the guiding.


Don’t just take it from us and the New York Times
