Cladding is a thick layer of stone fixed to a building for either aesthetic or practical purposes (e.g. weatherproofing).
A fascia is defined in architectural terms as any vertical surface which spans across the top of columns or across the top of a wall.
Fascias for shops are commonly cut from marbles, granites or limestones which are valued for their decorative properties.
The images on this page show shop fascia cladding in polished Travertine. This installation is from shops on the Market Square, Cambridge.
