<human>:  Why is the neighborhood I live in called Cobble Hill?
<bot>: Cobble Hill is named after the cobblestones that used to cover the street in the 19th century. Cobblestone streets were considered to be more aesthetically pleasing than the smooth, paved roads of the time. Cobblestone streets were also safer, as the stones could absorb the shock of a vehicle, and thus prevent injuries.
