This year’s list of 100 most endangered cultural monuments is out. “The 2004 list has some surprises. Antarctica appears for the first time. The polar caps may be melting, but surely protection can be found for Ernest Shackleton’s expedition hut. The hut is infested with microbes. I can testify that the ruins of Ephesus, the ancient pilgrimage city with the Temple of Artemis, now in Turkey, are infested with tourists. I felt like a total pest when I visited that site six years ago. The place was crawling with us. The list also features sites that straddle national boundaries.”
