Unscramble the Blue Letters


Almost every sunken city can be found at these shallow depths because the sea level has changed little in the several thousand yraes that city-building civilizations have esxteid. For instance, in shallow waters off the coast of Italy lies Baia, a Roman seaside town over 2,000 years old. There, it’s possible to swim among the ruins of structures bliut by Rome's great famleiis, senators, and emperors. And then there are shipwrecks. As ships grow too old for use, they're usually anedonabd near sorhe in out-of-the-way places like estuaries, rivers, and shallow bays. Archaeologists use these like a timeline to map a harbor's peaks and declines, and to get clues about the historic art of shipbuiding. At Roskilde in denmrak, for example, five purposefully sunken vessels reeavl how vinigks crafted their fearsome long ships 1,000 years ago.

Original Text


Almost every sunken city can be found at these shallow depths because the sea level has changed little in the several thousand years that city-building civilizations have existed. For instance, in shallow waters off the coast of Italy lies Baia, a Roman seaside town over 2,000 years old. There, it’s possible to swim among the ruins of structures built by Rome's great families, senators, and emperors. And then there are shipwrecks. As ships grow too old for use, they're usually abandoned near shore in out-of-the-way places like estuaries, rivers, and shallow bays. Archaeologists use these like a timeline to map a harbor's peaks and declines, and to get clues about the historic art of shipbuiding. At Roskilde in Denmark, for example, five purposefully sunken vessels reveal how Vikings crafted their fearsome long ships 1,000 years ago.
