Horses have been the back bone of human society for thousands of years. We have conquered countries, discovered new lands, made trade, and etc by means of horses. They were the most commonly used transportation of any kind in daily life until 100 years ago when cars entered into our modern life. Of course, foundation of New York City and Central Park were when horses were still important. City plan and Park plan were designed according to the traffic of horse and carriages. For example, the transverse paths of Central Park were originally designed for horse and carriages, and today they are used by motor vehicles. Like those paths, the horse and carriages are still in use. However, today they are only nostalgic figures of the city. They still serve human, this time to give experience of nostalgia and romantics, not to conquer new lands.
