 Large sections of the shore simply slid into the sea; and the beach area near Kamakura was raised up about six-feet; or in other words, where there had only been a narrow strip of sand along the sea, a wide expanse of sand was fully exposed above the waterline.Many temples founded centuries ago have required restoration, and it is for this reason that Kamakura has just one National Treasure in the building category (the Shariden at Engaku-ji).Much of Kamakura's heritage was for various reasons over the centuries first lost and later rebuilt.
