Lighthouse of Alexandria rises again as 22 massive blocks resurface from the seafloor after 2,000 years

Earlier this summer, archaeologists began hauling some of the giant granite blocks that once comprised one of the tallest buildings in the world out of the Alexandrian harbor after centuries underwater. Twenty-two blocks, to be precise, each one weighing between 80 and 90 tons with the operation requiring a boat, a platform, and a crane employing specific techniques to ensure the integrity of the blocks.
