Watch as Alex Krieger, professor and former chair of the Department of Urban Planning and Design, takes viewers on his iconic tour of Boston. Stopping at locations key to the growth of the city—from East Boston, which was once five islands that were consolidated in the late 18th to 19th century, to the Shawmut and South Boston Peninsulas—Krieger speaks of the historic and contemporary geographical, infrastructural, and racial conditions of Boston, a city in “constant need to create land.”
