Often overshadowed in people's minds by Paris, London is truly an artist's jewel. The art and architecture, history, gardens and museums are inspiring, yes, but there's so much more to this ancient city. The performances, attractions and markets are a boon to the creative soul. London can be surprisingly inexpensive to visit. Gazing at statues, browsing in bookstores, crossing the Thames on foot bridges, enjoying a "spot of tea"--all these and more are free, or nearly so.
