If you have a few hours to spare over the Easter holidays, can I recommend the C-Span special on the history of the Capitol.
Over three days, C-Span dedicated their time to broadcasting programmes which showed viewers around the US Congress building (the Capitol) - and looked in detail at its history. It is now available on the web at

Enjoy - and share with us your comments.
