Longfellow House Washington's Headquarters National Historic Site
Violent crime in Middlesex County is the sharpest concern for visitors here, with the surrounding Cambridge area logging a rate of 326.6 violent incidents per 100,000 residents in 2023 — notably higher than the Massachusetts state average. This is an urban historic site, not a remote park, so the risks visitors face look more like those of a city neighborhood than a wilderness campground. Thunderstorm wind events (22 recorded) round out the hazard picture but have caused no recorded deaths or injuries.
Because you're visiting a dense urban area, park your RV or tow vehicle in well-lit, designated lots and avoid leaving valuables visible inside. When thunderstorms roll through — and they do here regularly — move indoors immediately since the site's open grounds and tall trees offer no protection from gusty winds. Walk in groups after dusk and keep a close eye on children near the busy Cambridge streets bordering the property.
