The cliff has a more steep slope here than at other caves, so to achieve a tall grand facade it was necessary to cut far back into the slope, giving a large courtyard in front of the facade. There was originally a columned portico in front of the present facade, which can be seen "half-intact in the 1880s" in pictures of the site, but this fell down completely and the remains, despite containing fine carvings, were carelessly thrown down the slope into the river, from where they have been lost.
