I am not sure, that ancient artifacts are appealing for modern teenagers nowadays. It's better for them to visit some museums of Modern Arts, such as Pompidou Museum in Paris, where strange things of extraordinary shapes are on display. You can touch it without fear to break or damage it. Another museum which I consider a good place for youth is a Natural History Museum in London, where you can find remains of prehistoric creatures, dinosaurs' skeletons and some curious facts about life on the Earth before the humanity. I think these kinds of museums are very popular among young people nowadays.
