The Edward Hornblower House and Barn is a historic farmstead in Arlington, Massachusetts. The 2.5-story wood-frame house was built c. 1830, and was probably moved to its present location around 1850. At that time it also received stylistic modifications, giving it a more Italianate appearance. It was further modified in the 1870s, probably by financier Edward T. Hornblower, of the Boston brokerage firm Hornblower & Page (later Hornblower & Weeks) to add Renaissance Revival elements. A barn, estimated to date to about 1805, stands behind the house.[2]
