It contains houses, a church, commercial and industrial buildings dating from the mid-19th century to the early 20th century.","why_significant":"The district is argued to be significant under Criterion A for its ties to the Ohio River as a transportation route and to the growth of a working and middle-class riverside neighborhood that began as country estates. It retains a densely built, cohesive character with common Cincinnati building types and styles. The most prominent building is St. Martin's Church, built in 1892.","narrative":"Sedamsville River Road Historic District is a narrow strip of historic buildings on the north side of River Road in southwest Cincinnati, below the bluffs of Mount Echo Park and overlooking the Ohio River. It also takes in properties on Mount Hope and Mount Echo roads. The area began in the mid-nineteenth century as country estates for well-to-do Cincinnatians, then filled with smaller frame and brick houses on narrow lots, many reached by steep stairs and fronted by retaining walls. Commercial buildings, an early twentieth century industrial building and bungalows complete the mix. The most prominent building is St. Martin's Church, a High Victorian Gothic brick church built in 1892 with a 125-foot spire, now vacant and endangered. The district was listed for its connection to the Ohio River as a transportation corridor and for its surviving, densely built neighborhood character, despite demolitions from the 1948 city plan and 2003 road widening.","period_of_significance":null,"architect_builder":"Emil Baude (designer of St. Martin's Church, Resource 1)","architectural_style":"Mid-19th Century/Italian Villa; Late Victorian (Gothic, Italianate, Second Empire, Queen Anne, Stick); Late 19th & 20th Century Revivals (Colonial Revival, Tudor Revival, Italian Renaissance); Commercial; Bungalow/Craftsman","criteria":["A"],"status_note":"Mixed condition: some buildings have lost historic fabric or are neglected, and St. Martin's Church is vacant and endangered.
