Sacré-Cœur Basilica, Montmartre

The white-domed basilica on the hill of Montmartre, the highest point in Paris, finished in 1914. It's free to go in, and the steps in front of it give one of the best views over the city, especially at sunset. For an even better view, climb the dome (paid).

The funicular from the bottom of the hill takes a normal metro ticket, or you can climb the steps through the gardens. Be wary of the people around the bottom of the steps who try to tie 'friendship bracelets' on your wrist and then demand money. Next to the basilica, Montmartre's village streets lead to the Place du Tertre, the artists' square.
