O'Reilly Spite House
260 Concord Ave, Cambridge, MA 02138, USA
About
When a neighbor refused to buy his land in 1908, Francis O'Reilly built a house on it anyway... 37 feet long and only 8 feet wide. Just to be petty. The 308-square-foot building is still standing and now houses an interior design firm. Free, always visible from the street.
