Castner–Knott Building  The Caster–Knott Building is a historic building in Nashville, Tennessee. It is located on the corner of Church Street and 7th Avenue North in Nashville, Tennessee, at 616-618 Church Street. The Caster–Knott Building was built in 1906 for Charles Castner and William Knott's Castner–Knott Dry Goods Company. Founded in 1898, the store moved from its original location on 5th Avenue in what was the start of the city's westward expansion along Church Street. At that time, Caster–Knott was a single five story building with a 111-foot front at 618 Church street. Castner–Knott leased a portion of the building at 616 Church in 1933, a separate five story building constructed in 1911, with 28 feet fronting Church Street and as deep as the 618 Church building at 146 feet, adjacent to Capitol Boulevard. The top two floors were connected between 618 and 616 for Caster–Knott in 1936, the bottom three floors were connected in 1958–1959. It was renovated in 1958–1959, a small addition on the rear was added in 1975, and another renovation was done in the late 1990s after Castner–Knott went out of business in 1996. It has been added to the National Register of Historic Places listings in Davidson County, Tennessee since August 20, 1999.
