>I like it because it confirms my thoughts about the place being a stone mind prison.<

What's a stone mind prison?

Time-hallow'd pile by simple builders rear'd!
Mysterious round, through distant times rever'd!
Ordained with earth's revolving orb to last!
Thou bringst to sight the present and the past.
Rapt with her theme, bold Fancy wings her flight
To silent ages long involved in night
Bids clouded forms arise to sight display'd
And scatters light along th' oblivious shade.

John Ogilvie (1733-1813)*
