The author of the article is not given at The Free Library, but I love some of the words he or she used when describing cemeteries:
Forget landmarks such as the Eiffel Tower, the Empire State Building or the Colosseum; cemeteries are the punctuation marks in between, quiet islands amid the city racket. A great one is an architectural jewel in its own right, a Vanity Fair party of spot-the-dead-celebrity, a stark warning from history, a store of cracking anecdotes or a life-affirming communion with past generations.and...
Above all, I love cemeteries because they make the past tangible, like a fading photograph or great-grandmother's hairbrush.
Also mentioned in the article are the Highgate Cemetery in London, the Pierre-Lachaise in Paris, and the Normandy American Cemetery & Memorial. Check it out!
