Here is another photo from the experiments section of our archive – Tower 15x12 (247 blocks). Yes, you can see the grass through that window! The blocks are rough and uneven – we were still in search for quality material.
A picture from our archive: An experimental Fortress 17x24 without the base. It was cast of self-levelling floor in 2013 to test the moulds.
We did it! A milestone, really.
