The second most interesting thing about Bulla Regia, after the underground mansions, are the many clear examples of ancient air conditioning systems and toilets. An important, trivial thing which usually has been flushed into history's oblivion. But if you ask yourself when standing in an ancient ruin how people solved all those little everyday problems, it can be hard to imagine the answer. At Bulla Regia some good examples of just that have survived!
Twin toilet.
