After Notre Dame we walked to Sainte Chapelle to see the extraordinary chapel. We got stuck in a line for a while to get through the Palais du Justice security checkpoint but it was completely worth it! The stained glass in Sainte Chapelle is phenomenal and unlike anything I had ever seen before. Mind boggling when you remember that this was completed in 1248! I wonder if Louis IX really did buy Jesus’ Crown of Thorns? He paid three times as much for the supposed Crown of Thorns than it cost to create the remarkable Sainte Chapelle built to house it!
