Years ago, there?s this area in Boston called the Back Bay. It was quite literally named because it?s actually just an inland bay along the peninsula where Boston was. Often, this place was flooded by the Charles River. But in the 1820?s, an enterprising mill company built a dam along what is now Beacon Street.

50 years passed and the landfill was finally finished. The Commonwealth Avenue Mall became the main attraction within the elegant new Back Bay neighbourhood.

The Commonwealth Avenue Mall is a big 32 acres. It?s designed in the French boulevard style by Arthur Gilman in 1856. The Commonwealth Avenue Mall is known for its lush greenery. It?s most famous for having the magnificent American elms, some of which survived the Dutch elm disease that devastated the species in recent decades. Now, the Commonwealth Avenue Mall is considered to be one of the finest streets in the city.
