Old Courthouse, also known as the Buena Vista Land Company building, is a historic courthouse building located at Buena Vista, Virginia. It was built in 1890, and is a 2 1/2-story, brick building with a mansard roof in the Second Empire style. It originally housed the Treasurer's Office, Mayor's Office, Office of the Clerk of Court, the courtroom Attorney's offices, the telephone exchange, and the local Odd Fellow's Lodge. The local public library has occupied the building since 1971, after a new municipal building was constructed.
