Charles River in the context of "Newton, Massachusetts"

Paul Revere's midnight ride was an alert given to minutemen in the Province of Massachusetts Bay by local Patriots on the night of April 18, 1775, warning them of the approach of British Army troops prior to the battles of Lexington and Concord. In the preceding weeks, Patriots in the region learned of a planned crackdown on the Massachusetts Provincial Congress, then based in Concord, by the British occupational authorities in the colony.

Sons of Liberty members Paul Revere and William Dawes prepared the alert, which began when Robert Newman, the sexton of Boston's Old North Church, used a lantern signal to warn colonists in Charlestown of the British Army's advance by way of the Charles River. Revere and Dawes then rode to meet John Hancock and Samuel Adams in Lexington, ten miles (16 km) away, alerting up to 40 other Patriot riders along the way. Revere and Dawes then headed towards Concord with Samuel Prescott.

Cambridge (/ˈkeɪmbrɪdʒ/ KAYM-brij) is a city in Middlesex County, Massachusetts, United States. It is a suburb in the Greater Boston metropolitan area, located directly across the Charles River from Boston. The city's population as of the 2020 U.S. census was 118,403, making it the most populous city in the county, the fourth-largest in Massachusetts behind Boston, Worcester, and Springfield, and ninth-most populous in New England. The city was named in honor of the University of Cambridge in Cambridge, England, which was an important center of the Puritan theology that was embraced by the town's founders.

Founded in December 1630 during the colonial era, Cambridge was one among the first cities established in the Thirteen Colonies, and it went on to play a historic role during the American Revolution. In May 1775, approximately 16,000 American patriots assembled in Cambridge Common to begin organizing a military retaliation against British troops following the Battles of Lexington and Concord. On July 2, 1775, two weeks after the Second Continental Congress in Philadelphia formally established the Continental Army and appointed George Washington commander of it, Washington arrived at Cambridge Common to take command of the Patriot soldiers camped there. Many of these soldiers played a role in supporting Washington's successful siege of Boston, which trapped garrisoned British troops from moving by land, forcing the British to ultimately abandon Boston. Cambridge Common is thus celebrated as the birthplace of the Continental Army.

George Eastman (July 12, 1854 – March 14, 1932) was an American innovator and entrepreneur who founded the Eastman Kodak Company and helped to bring the photographic use of roll film into the mainstream. After a decade of experiments in photography, he patented and sold a roll film camera, making amateur photography accessible to the general public for the first time. Working as the treasurer and later president of Kodak, he oversaw the expansion of the company and the film industry.

Eastman was a major philanthropist, establishing the Eastman School of Music, Rochester Philharmonic Orchestra, and schools of dentistry and medicine at the University of Rochester and Eastman Dental Hospital at University College London, and making large contributions to the Rochester Institute of Technology (RIT), the construction of several buildings at the second campus of Massachusetts Institute of Technology (MIT) on the Charles River, and Tuskegee University and Hampton University, two historically black universities in the South. With interests in improving health, he provided funds for clinics in London and other European cities to serve low-income residents.

The Big Dig was a megaproject in Boston that rerouted the elevated Central Artery of Interstate 93 into the O'Neill Tunnel and built the Ted Williams Tunnel to extend Interstate 90 to Logan International Airport. Those two projects were the origin of the official name, the Central Artery/Tunnel Project (CA/T Project). The megaproject constructed the Zakim Bunker Hill Bridge over the Charles River, created the Rose Kennedy Greenway in the space vacated by the previous elevated roadway and funded more than a dozen projects to improve the region's public transportation system. Planning began in 1982 and construction was carried out between 1991 and 2006. The project concluded in December 2007.

The project's general contractor was Bechtel, with Parsons Brinckerhoff as the engineers, who worked as a consortium, both overseen by the Massachusetts Highway Department. The Big Dig was the most expensive highway project in the United States, and was plagued by cost overruns, delays, leaks, design flaws, accusations of poor execution and use of substandard materials, criminal charges and arrests, and the death of one motorist.

The Muddy River is a series of brooks and ponds that runs through sections of Boston's Emerald Necklace, including along the south boundary of Brookline, Massachusetts (a town that went by the name of Muddy River Hamlet before it was incorporated in 1705). The river is a protected public recreation area surrounded by parks and hiking trails, managed by the Massachusetts Department of Conservation and Recreation.

The river flows from Jamaica Pond through Olmsted Park's Wards Pond, Willow Pond, and Leverett Pond. It then flows through a conduit under Route 9 and into a narrow park called the Riverway, from which it flows through three culverts: the Riverway Culvert, the Brookline Avenue Culvert, and the Avenue Louis Pasteur Culvert. The Muddy River continues from the Fens toward its connection with the Charles River via the Charlesgate area, running through a stone-paved channel surrounded by a narrow strip of parklands. In a series of stone bridges and tunnels, it passes under Boylston Street, Massachusetts Turnpike, Commonwealth Avenue, Storrow Drive, and a series of elevated connecting ramps (the Bowker Overpass).

Charlestown is the oldest neighborhood in Boston, Massachusetts, in the United States. Also called Mishawum by the Massachusett, it is located on a peninsula north of the Charles River, across from downtown Boston, and also adjoins the Mystic River and Boston Harbor waterways. Charlestown was laid out in 1629 by engineer Thomas Graves, one of its earliest settlers, during the reign of Charles I of England. It was originally a separate town and the first capital of the Massachusetts Bay Colony.

Charlestown became a city in 1848 and was annexed by Boston on January 5, 1874. With that, it also switched from Middlesex County, to which it had belonged since 1643, to Suffolk County. It has had a substantial Irish-American population since the migration of Irish people during the Great Irish Famine of the 1840s. Since the late 1980s, the neighborhood has changed dramatically because of its proximity to downtown and its colonial architecture. A mix of yuppie and upper-middle-class gentrification has influenced much of the area, as it has in many of Boston's neighborhoods, but Charlestown still maintains a strong Irish-American population.
