Just a street scene on Beacon Hill. These streets were quite nice, and there were a number of new buildings, built in sympathy wit the existing structures. It's probably comparable to Paddington in Sydney.
The brass ducks allow children plenty of room burn off energy.
These are called Swan Boats presumably because the captain/operator sits in the swan at the back. They are peddle powered, and circulate around a small lake.
The lake, with the John Hancock tower in the background. John Hancock (1737 - 1793) was a merchant and financial backer of the early days of the War of Independence.
If you ever watched the TV series Cheers well here is the building used for the opening shots. It is on Beacon Street, opposite Boston Botanical Gardens.
You can just make out the sign in this image.
