Of course many buildings have been demolished in Grasse over the years, but it's possible to use AI to help to see them as they once were.  Here are three: Alice de Rothschild's Villa Victoria (see my post here); the old Gare du Sud when Grasse had two railways; and Chateau Isnard, prominent next to Cours Honoré Cresp (see here).  Click to see the video (on your mobile, it's better in landscape mode).
