As one of the oldest cities in the United States, Boston has deep roots in early America and a host of memorials and monuments to prove it. Harvard, the oldest university in America, was established here in 1636. Nowadays Boston has a seasonal population of 100,000 college students. Boston is a good city to walk in, so park your car and visit the Boston Common and the Public Garden. Follow the signs painted red and walk through the 2.5-Km Freedom Trail around the city's main historical sights: Park Street Church, King's Chapel, the Old South Meeting House, the Old State House, Faneuil Hall, North End, Paul Revere House, Old North Church and Beacon Hill. Also worth a visit are Marketplace Center and Quincy Market. From the Charles River one can have a dramatic view of Boston skyline: the 60-story John Hancock Building, the Prudential Tower and Copley Place. On the other side of the river is MIT, in Cambridge and Charlestown.
