Boston, MA
Opened 1923 as a small military airfield on Boston Harbor landfill. Renamed in 1956 for Edward Lawrence Logan, the WWI Army Air Service general. Built and steadily expanded into the harbor — surrounded by water on three sides. American Flight 11 and United 175 — the two Boeing 767s that struck the World Trade Center's North and South Towers on September 11, 2001 — both departed Logan that morning.
Boston Light on Little Brewster Island has guided ships into Boston Harbor since 1716 — the oldest continuously operating lighthouse station in the United States. The current 89-foot stone tower was rebuilt in 1783 after the British blew up the original on their retreat from Boston Harbor in 1776. The harbor itself is dotted with 34 islands, most preserved as a national recreation area: drumlin islands left by retreating glaciers, Civil War-era forts on Castle and Georges, and the lonely whitewashed cone of Long Island Head Light visible from the airline approach into KBOS. The harbor cleanup from 1986-2000 turned what was once one of the dirtiest harbors in America into swimmable water.
A small public memorial in downtown Salem, Massachusetts, dedicated August 5, 1992 by Elie Wiesel — 300 years after the 1692 witch trials. Twenty granite benches cantilever from a stone wall surrounding a small plot adjacent to the Old Burying Point, one for each of the 20 people executed (19 hanged at Proctor's Ledge, 1 — Giles Corey — pressed to death under stones for refusing to enter a plea). The Salem witch hysteria began in February 1692 when several young girls in the Reverend Samuel Parris's house began having fits attributed to witchcraft; over the next ten months, more than 200 people were accused and 30 found guilty. The trials ended when Governor William Phips dissolved the special court after his own wife was accused. Salem today balances genuine memorial (the Witch Trials Memorial, the Salem Witch Museum's educational mission, the Proctor's Ledge Memorial added in 2017) with Halloween commercialization that runs October through November. The Peabody Essex Museum nearby holds the largest Asian art collection of any U.S. museum — built on Salem's 18th-19th century trading wealth.
A 61-acre kettle pond in Concord, Massachusetts — formed about 12,000 years ago when a buried block of glacial ice melted, leaving a deep depression that filled with groundwater. Henry David Thoreau built a 10-by-15-foot cabin on the pond's north shore on July 4, 1845, and lived there for two years, two months, and two days while writing the manuscript that became "Walden, or Life in the Woods" (1854) — the founding text of American environmentalism and the inspiration for everything from John Muir to the modern Sierra Club. The original cabin is gone, but a stone-cairn memorial marks its exact site, and a full-scale replica sits at the entrance to Walden Pond State Reservation. Ralph Waldo Emerson, who owned the land Thoreau built on, lived a mile away in Concord and is buried with Thoreau and Louisa May Alcott and Nathaniel Hawthorne in Sleepy Hollow Cemetery's "Authors' Ridge." The pond water is famously clear — Thoreau measured its depth (102 feet) and clarity with care; the data still informs modern limnology. The North Bridge in Concord, where the "shot heard 'round the world" opened the American Revolution on April 19, 1775, is 1.5 miles north.
On Warren Avenue in Plymouth, Massachusetts — a living-history museum complex (rebranded 2020 from "Plimoth Plantation" to recognize the Indigenous Patuxet community whose land it sits on) preserving the story of the 1620 Mayflower landing and its consequences. Two reconstructed villages: the 17th-Century English Village shows the Pilgrim settlement as it appeared around 1627, with costumed role-players speaking in period dialect maintaining specific historical personas; the Patuxet Homesite (formerly Wampanoag Homesite) shows Wampanoag life of the same period, staffed by Native interpreters speaking from their own perspective rather than playing roles. Three miles east on Plymouth Harbor, the Mayflower II — a full-scale 1957 replica built in Brixham, England and sailed across the Atlantic — sits at the State Pier; in 2020 she completed a five-year restoration in time for the 400th anniversary of the original 1620 voyage. Plymouth Rock itself, in a granite-columned canopy on the harbor edge, is a glacial erratic boulder traditionally identified as the Pilgrims' landing spot — though no contemporary 1620s document mentions it, the identification dating only to 1741.
