High Quality Content by WIKIPEDIA articles! Sacred Heart Academy is a registered historic building in Cincinnati, Ohio, listed in the National Register on April 11, 1973. Cincinnati is considered to have been the first American boomtown in the heart of the country in the early nineteenth century to rival the larger coastal cities in size and wealth. As the first major inland city in the country, it is sometimes thought of as the first purely American city, lacking the heavy European influence that was present on the east coast. However, by the end of the nineteenth century, Cincinnati's growth had slowed considerably, and the city was surpassed in population by many other inland cities.
