Quite simply the most impressive museum I’ve ever set foot in. There’s a breathtaking array of items, many of which date back thousands of years and come from all over the world. I was struck by the beauty of the Greek and Roman collection (statues, amphorae, armour and so on), as well as the Byzantine art (particularly the chalices pictured above). If you ever do go to New York, this is a must-see destination, though make sure to set yourself at least a day to walk around it all. I can’t think of anywhere quite like it.
