Today, countries like United Kingdom, Canada, Australia, India, South Africa, New Zealand, and many other member states in the Commonwealth of Nations are honoring the lives and sacrifcies of those who served in World War I with Remembrance Day. It also coincides with Veterans Day in the United States. The most familiar symbol of this memorial day is the red poppy.

These poppies have bloomed across the battlefields of World War I—their red shades so intense that they bear a resemblance to the blood spilled during the war. In honor of Remembrance Day, here are some remarkable photos of poppies captured by 500px photographers.

From the blood-red ceramic poppies flooding the Tower of London to sweeping fields bursting with poppies, scroll down and take the time to commemorate history’s fallen soldiers.
