A new £26 million building, completed in September 2008, has replaced the original block.
The second and third were each halves of the original blocks that had stood at one and two.
Since then, more facilities have been added to the college, with an extension to the original block, and a refurbishment in the 1980s.
The original block is as good as new after the erase.
But Rund acted as selling agent for all the original blocks.
The original blocks are also held in the collection of the Albertina.
The original block, dated to about 1750, is a two bay stone one story, one room structure.
This is also supported by a family legend that the original main block burned to the ground.
The original block opened in 1993 contains several public art installations.
The remainder of the original block is used for the sanctuary, a barrel-vaulted square room.
