In every collection of pictures of London you have seen the Houses of Parliament there nexst to the River Thames.
When you visit London, be sure to include a day that is not on the weekend. Westminster Abbey, St. Paul's Cathedral, and some other sites are closed on Sunday. If you do not plan carefully, you will find yourself settling for the magnificent exterior views as we did.
But that's good, too. And a good excuse to come back again some day.
Architecture is always good for Geometry Monday.
