Nice door on the Magna Carta album cover. I wonder why it is there?

Here is some LOST-flavored text from the original Magna Carta document:

"No free man shall be taken or imprisoned or dispossessed, or outlawed, or banished, or in any way destroyed, nor will we go upon him, nor send upon him, except by the legal judgment of his peers or by the law of the land....To no one will we sell, to no one will we deny, or delay right or justice."
