Basilique du Sacré Cœur from downhill Welcome to Day 2 of my return to Paris. Today we go up the Montmartre butte, which is the highest point in Paris and where the Basilique du Sacré Cœur sits. The church is one of the most identifiable landmarks in the Paris landscape and easily seen from any unobstructed vantage point. Up there we’ll visit the Dali museum and check out the sights around the church.
