Also known as the "Blacksmith House," this yellow Colonial is now owned by the Cambridge Center for Adult Education. The tree itself is long gone, but this spot inspired Longfellow's lines: "Under a spreading chestnut tree, the village smithy stands." The blacksmith's shop, today commemorated by a granite marker, was next door, at the corner of Story Street. From October to December, the celebrated Blacksmith House Poetry Series runs most Monday nights. Tickets are $3.
