The first aerial images of the 2019 rally in Barcelona for Catalonia's National Day, the Diada. This is how the central focus of the protest, Plaça de España, appeared at 4:15pm, that is, almost exactly one hour before the start of the rally.
Aerial view of the Diada at 4:55pm.
Aerial images of the rally at the official start time: 5:14pm. (This symbolic time,17.14h in the 24-hour clock, reflects the origins of the National Day, when the besieged city of Barcelona fell to Bourbon conquest on September 11th, 1714.)
The view from above the Diada rally at 5:45pm, midway through the speeches.
