THE ELABORATE DOORWAY PROCLAIMS THAT THIS HUGE ROCK MASS, WITH ITS 



HUNDREDS OE CHAMBERS, WAS A PALATIAL RESIDENCE IN OLDEN 



TIMES, BUT NOW IT IS GIVEN OVER TO PIGEONS 



The holes of ingress and egress for the pigeons are seen in the background of the two great 



openings in the wall. 



IN THESE MASSES THE PROCESS OE DISINTEGRATION WAS RETARDED BY THE 

 SUPERINCUMBENT LAYER OE LAVA 



This was evidently a fashionable street in Trogloville, if we may judge by the numerous 

 rectilinear, and therefore decorative, window openings. They are too small to be exposed 

 chambers that were once inside the cliffs.
