Parallel with Field street, Bobrecka Hillock street (nowadays H. Przepilinskiego) was situated on the border line between Cieszyn and Bobrek. One would think that the name originates from its situation above the valley of Bobrówka. Bobrecka Hillock street was mostly built over by low, one-storeyed houses occupied by less wealthy people, among others, by several watch-makers.
