The East Cambridge Historic District encompasses the historic center of East Cambridge, Massachusetts. It includes the major buildings that were built to house county services for Middlesex County beginning in the 1810s, and a cluster of largely vernacular Greek Revival worker housing located west of the county complex on Otis, Thorndike, Spring, and Sciarappa Streets.

The Middlesex County Courthouse is a historic courthouse building in East Cambridge, Massachusetts. It was initially designed in 1814-1816 by noted architect Charles Bulfinch (1763–1844), and subsequently enlarged in 1848 by Ammi B. Young. The original courthouse was given by Andrew Craigie as part of his scheme to develop East Cambridge. Bulfinch created its plans, and it was erected 1814-1816 on Third Street between Otis and Thorndike Streets. His original stuccoed building is now known by only one surviving sketch, and forms the central core of today's building. In 1848 architect Young enlarged and refaced the building in brick, adding late Federal and Greek Revival details such as a monumental cupola, Palladian windows, and recessed wall arches. A later 1924 addition obscured his 1848 entry facade. In 1973 the buildings were slated for demolition to make a parking lot, but saved by a preservation effort led by architect Graham Gund. Restoration efforts removed the 1924 addition, recreated Young's entry portico, restored its large clock tower, and cleaned and repaired the cupola's gold dome, brickwork, cast-iron trim, wrought-iron fencing, and slate and copper roofs. Other buildings in the restored Bulfinch Square include the imposing Registry of Deeds and Probate Court (1896) with its four giant brick-columned porticoes, the Clerk of Courts Building (1889), and the Third District Court Built (1931, architect Charles Greco). The Middlesex County Courthouse building is situated adjacent to the iconic 16 story former Edward J. Sullivan "Hi-rise" Superior court building.

The Inner Belt District is a 126-acre (0.51 km2) industrial district located in the southeastern portion of Somerville, Massachusetts. Along with nearby Brickbottom, the Inner Belt is a historically industrial zone of Somerville, with factories, warehouses, distribution centers, railroad connections, regional maintenance facilities, MBTA and Amtrak offices, retail stores and a hotel. Named after the proposed but doomed Inner Belt Highway, the district is bounded by Interstate 93, Route 28, and the Lowell and Fitchburg rail lines. Inner Belt Road runs through the center of the Inner Belt District intersecting with 3rd Avenue to connect to the MBTA maintenance facility. Although adjacent to the McGrath Corridor, NorthPoint in Cambridge and Sullivan Square in Charlestown, it is isolated from them by highways and rail lines.An elevated railroad right-of-way separates the Brickbottom area located to the west of the Inner Belt District. The two areas resemble each other in terms of use. However, Brickbottom has older dense development in a grid pattern and has a couple of small neighborhoods. Somerville is currently engaged in an ongoing community process, begun in 2011, to determine a long-term Master Plan for the Inner Belt and Brickbottom region. A draft of the plan should be available for public comment by the end of 2013.

The building at 42 Edward J. Lopez Avenue is a rare Federal period house in East Cambridge, Massachusetts. The two story wood-frame building has a hip roof and very simple styling. It was built about 1830, during the first period of East Cambridge's development after construction of the West Boston Bridge, and was moved to its present location c. 1900, probably as part of construction work in the area. The nature of the terrain in the area at that time means it cannot have been moved very far.The house was listed on the National Register of Historic Places in 1982.
