Unlike the casual, chaotic way in which early Boston was laid out, the streets of Back Bay are arranged in an orderly grid.  Renowned for its elegant homes, the architectural marvels of Copley Square, and its signature stately boulevard, Commonwealth Avenue, the Back Bay is one of Boston’s most charming neighborhoods. On this tour you will learn how the Back Bay, once an actual body of water, was filled in and how the neighborhood was developed in the mid-1800s to become one of America's richest collections of art and architecture. The treasures of the Back Bay tour include Trinity Church, the Boston Public Library, Old South Church and the grand Back Bay townhouses. Walk back in time to view splendid examples of Victorian architecture.
