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.
