<Tr> <Th> Added to NRHP </Th> <Td> 1970 </Td> </Tr> <P> Plymouth Rock is the traditional site of disembarkation of William Bradford and the Mayflower Pilgrims who founded Plymouth Colony in 1620 . The Pilgrims did not refer to Plymouth Rock in any of their writings; the first known written reference to the rock dates to 1715 when it was described in the town boundary records as "a great rock ." The first documented claim that Plymouth Rock was the landing place of the Pilgrims was made by Elder Thomas Faunce in 1741, 121 years after the Pilgrims arrived in Plymouth . From that time to the present, Plymouth Rock has occupied a prominent spot in American tradition and has been interpreted by later generations as a symbol both of the virtues and flaws of the first English people who colonized New England . In 1774, the rock broke in half during an attempt to haul it to Town Square in Plymouth . The top portion (the fragment now visible) sat in Town Square, was moved to Pilgrim Hall Museum in 1834, and was returned to its original site on the shore of Plymouth Harbor in 1880 . Today it is ensconced beneath a granite canopy designed by McKim, Mead & White . </P> <P> Plymouth Rock is geologically classified as a Dedham Granite boulder and a glacial erratic . The two most significant primary sources on the founding of Plymouth Colony are Edward Winslow's Mourt's Relation and Bradford's history Of Plymouth Plantation, and neither refers to Plymouth Rock . The rock first attracted public attention in 1741 when the residents of Plymouth began plans to build a wharf which would bury it . Before construction began, a 94 - year - old elder of the church named Thomas Faunce, then living three miles from the spot, declared that the boulder was the landing place of the Mayflower Pilgrims . He asked to be brought to the rock to say a farewell . According to Plymouth historian James Thacher: </P> <P> A chair was procured, and the venerable (Faunce) conveyed to the shore, where a number of the inhabitants were assembled to witness the patriarch's benediction . Having pointed out the rock directly under the bank of Cole's Hill, which his father had assured him was that which had received the footsteps of our fathers on their first arrival, and which should be perpetuated to posterity, he bedewed it with his tears and bid to it an everlasting adieu . </P>
