The #1 thing you have to see in Lexington is the Lexington Green, located at 1625 Massachusetts Ave, Lexington, MA 02421. This is the site of the first shots fired in the Revolutionary War at the Battle of Lexington and Concord on April 19, 1775.
While you’re there seeing the first monument erected in honor of the Revolutionary War you can hop over to the Hancock-Clarke House at 36 Hancock Street which is where notable revolutionaries John Adams and John Hancock stayed the night before the Battle of Lexington and Concord. This house is also the only surviving home that John Hancock ever lived in, though it was only for a short time as a boy. It’s also the house that Paul Revere stopped at on his famous “Midnight Ride” to alert the colonists that the British were coming.
On 1332 Massachusetts Street there’s another historical house in connection with the Battle of Lexington and Concord called the Munroe Tavern. The Tavern was used as a colonial meeting spot the day before the fighting broke out and shortly after the battle was taken by British soldiers and used as a field hospital. Notably, George Washington dined here on a 1789 trip to visit the Battlefield at Lexington Green. His notes and documents relating to the trip are on display upstairs on the table that he sat at during his visit. The Tavern also now contains the Museum of the British Redcoats which lets visitors see what the fighting was like on April 19, 1775, for the British soldiers.
If after seeing all these historical sites you’re ready to get up and move around a little bit, there are plenty of outdoor trails and parks but the best has to be The Middlesex Fells Reservation on 4 Woodland Rd. With over 100 miles of trails that are open to hiking, mountain biking, cross-country skiing, and horseback riding there’s plenty to do on foot, and there’s also a concessionaire that offers sailing lessons along with rentals of kayaks, canoes, pedal boats, and row boats.
Mountain climbing is also very popular with people in the area. After this walking around though you’ll have to be pretty hungry and the best place to eat is The Artistry on the Green at 2027 Massachusetts Ave. If you choose to stay at the attached Bed and Breakfast you’ll receive a free breakfast with plenty of options such as omelets, chef’s pastry of the day, though my favorite is the french toast with blueberry compote. If you’re there for dinner, trying their New England Clam Chowder is an absolute must. Lexington is where you’ll also find Lice Happens.
