Looking back over some previous posts, I thought I would check and update some holiday-themed posts.

An Italian holiday included a visit to the wonderful **National Cinema Museum in Turin **– see the **Mathematics in the Movies** post (now with added songs!)

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

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

**buildings.**Note the different types of queries possible – simply type in the name of a building for information, for example, see

I do like to keep my eye open for mathematical pictures (**Tetrahedral Numbers on Mathisfun**), hence:
