I took the Metro (subway) on my last morning in Prague to visit the Dancing House, an avant-garde building which is supposed to vaguely resemble a pair of dancers.
Located by the river, it has an elevator to the top (no steps to climb!) and beautiful views from the top.
Here are some views of, and from, the Dancing House. Enjoy!
