So, visiting Milan and wandering round the lovely Cathedral (one of the largest in Europe) I was struck by the geometry all around!

This week – in holiday mode some interesting sites on Mathematics and architecture:

From Tripbase, **9 Most Mathematically Interesting Buildings in the World **and from Flavorwire, **10 Amazing Examples of Architecture Inspired by Mathematics. **There is some overlap between these two lists, both mention quite rightly the cathedral in Barcelona Designed by Antoni Gaudi. For some great mathematical photos from Barcelona – **see these previous two posts**.

For some further reading Plus Magazine has an article on **Perfect buildings: the maths of modern architecture by Marianne Freiberger.**

Marcus du Sautoy’s,

**Maths in the city**site includes a suggested**tour of London**which looks at networks, geometry, resonance, curves and topology through the medium of chalk, sweeties, slinkies and rope!The London tour includes St Paul’s Cathedral, John Shortt has written a

**Maths trail for Saint Paul’s**, the ideas from which could also be used for other buildings. ….

WolframAlpha can be used for information on

**buildings.**Note the different types of queries possible – simply type in the name of a building for information, for example see**Eiffel Tower**or enter two buildings for a comparison. It is also possible to look up**properties of buildings,**did you know that the**Empire State Building has 102 floors**?! …

**A great resource on TES**for when we get back to school is Laura Wilson’s Plans and Elevations, a PowerPoint of images showing the plans and elevations of some famous buildings.
