Castle Street Row
Why it's listed
Eight brick row houses at 4-18 Castle Street in Worcester form the city's largest block of row houses. Built around 1873 in the Second Empire style, each unit rises two and one-half stories above a high basement and has a side-hall plan, a three-sided bay window, a bracketed entry porch and a mansard roof with dormers. The lower four units are arranged symmetrically around two sets of paired entries, while the upper four have individual entries set at staggered heights that follow the slope of the hill. The land was once part of the Oread Institute, a women's college founded by Eli Thayer in 1849. In the early 1870s Thayer subdivided part of the campus into small, narrow lots, nearly all bought by the local builder Larkin Gates. Gates built forty-two houses in eight rows, and only this one survives intact. Though designed as modest single-family homes, many were later divided into apartments or used for boarders. Row houses remain rare in Worcester.
Significance in brief: It is Worcester's largest block of row houses and the only one of eight rows built by Larkin Gates in the area that remains intact. The row grew out of Eli Thayer's subdivision of the former Oread Institute campus. Row houses have been rare in Worcester, and Castle Street holds the city's largest concentration.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved.
