Egg Rock is an outcrop of Silurian Straw Hollow Diorite at the confluence of the Assabet and Sudbury rivers, where they form the Concord River in Concord, Massachusetts. The outcrop is located on a roughly oval intermittent island of about 100 by 50 meters. Egg Rock is usually accessible using foot trails over land, but during high river levels the island is separated from the mainland by a narrow channel. The highest point of Egg Rock is about 39 meters above mean sea level and about 6 meters above normal river level. The United States Geological Survey (USGS) Geographic Names Information System (GNIS) includes Egg Rock as GNIS feature 617309, classified as an island. In the GNIS database as of February 2010, the listed position (latitude 42.4645383, longitude -71.3592266) is misplaced by about 125 meters to the southwest, and is not actually located on the intermittent island. A more correct position is latitude 42.4651, longitude -71.3585.

The Sudbury River is a 32.7-mile-long (52.6 km) tributary of the Concord River in Middlesex County, Massachusetts, in the United States.Originating in the Cedar Swamp in Westborough, Massachusetts, near the boundary with Hopkinton, the Sudbury River meanders generally northeast, through Fairhaven Bay, and to its confluence with the Assabet River at Egg Rock in Concord, Massachusetts, to form the Concord River. It has a 162-square-mile (420 km2) drainage area. A 1775 map identifies the river by this name as passing through the town of Sudbury, itself established 1639. On April 9, 1999, nearly 17 miles (27 km) of the river were "recognized for their outstanding ecology, history, scenery, recreation values, and place in American literature," by being designated as a part of the National Wild and Scenic Rivers System. The 14.9-mile (24.0 km) segment of the Sudbury River beginning at the Danforth Street Bridge in the city of Framingham, downstream to the Route 2 bridge in Concord, is designated as a Scenic River, and the 1.7-mile (2.7 km) segment from the Route 2 bridge downstream to its confluence with the Assabet River at Egg Rock is designated as a Recreational River, along with adjoining stretches of the Assabet and Concord rivers.Mercury contamination was discovered in the 1970s from the Nyanza plant in Ashland. The EPA subsequently listed the town as a toxic site and led a cleanup effort to repair the damage. It is still recommended that fish caught downriver not be eaten.

The Minute Man is an 1874 sculpture by Daniel Chester French in Minute Man National Historical Park, Concord, Massachusetts. It was created between 1871 and 1874 after extensive research, and was originally intended to be made of stone. The medium was switched to bronze and it was cast from ten Civil War-era cannons appropriated by Congress. The statue depicts a minuteman stepping away from his plow to join the patriot forces at the Battle of Concord, at the start of the American Revolutionary War. The young man has an overcoat thrown over his plow, and has a musket in his hand. Nineteenth-century art historians noticed that the pose resembles the pose of the Apollo Belvedere. Until the late twentieth century, it was assumed that the pose was transposed from the earlier statue. Based on Daniel Chester French's journals, modern art historians have shown that the Apollo Belvedere was only one of several statues that were used in the research for The Minute Man. The statue was unveiled in 1875 for the centennial of the Battle of Concord. It received critical acclaim and continues to be praised by commentators. The statue has been a suffragette symbol and a symbol of the United States National Guard and its components, the Army National Guard, and the Air National Guard, and depicted on coins such as the 1925 Lexington–Concord Sesquicentennial half dollar and the 2000 Massachusetts state quarter.

There are claims that the blockhouse was moved from near Main Street northeast of the South Burying Ground, where it was the home the Rev. John Jones, a minister and founder of Concord, who was alleged to have built it as early as 1635/1636.
