What are the holes for?

Lopud island has many fine examples of these stone features on the properties. Dubrovnik Old Town has many too, but a lot were damaged during the siege. "What are the holes for?" people ask. Well in days gone by a stick would be threaded through, and fabric wrung out with cold water would be hung on the stick, so that the breeze would waft cooler air into the house. Great invention of early air-conditioning!
