At the Plaza de la Democracia y de la Abolición del Ejército there is this massive glass and metal circle. As I wandered around, inside I found a stone circle. Hundreds of these circles are found all over Costa Rica, and this one sits right outside the Museo Nacional de Costa Rica. They don’t know why they were but they are from the Precolumbian era.
