Mayflower Rock Memorial in Plymouth, Massachusetts

Quoting from Wikipedia: Plymouth Rock:

Plymouth Rock is the traditional site of disembarkation of William Bradford and the Mayflower Pilgrims who founded Plymouth Colony in December 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.

In 1774, the rock broke in half during an attempt to haul it to Town Square in Plymouth. One portion remained in Town Square and was moved to Pilgrim Hall Museum in 1834. It was rejoined with the other portion of the rock, which was still at its original site on the shore of Plymouth Harbor, in 1880. The rock is now ensconced beneath a granite canopy designed by McKim, Mead & White.

It is a nice tradition and it is a beautiful place. The rock in on the beach under the "canopy" you can see in the middle of the photo.
