I had the chance to attend the Palm Sunday procession in Madrid before heading off to Paris. People started lining up well in advance to get the best view of the procession. The entire procession took about two hours. It was amazing watching the statues being paraded through the street! The statues are enormous and moved using solely manpower. Every time the statue completed a turn, the crowd applauded. You can check out a video I took at the procession here.
