This snap really appeals to me.
It’s a juxtaposition of protection in the southern French village of Arles. In the foreground, modern protection against Covid; in the background, medieval protection against lawless threats. And on the side, that column you see is the sensor for a bollard, a modern traffic barricade that helps keep the inner city streets free from the threat of terrorists using their vehicles as weapons.
All three things serving a very similar purpose, keeping out something that is unwanted.
