A beautiful, huge medieval castle in an ice plains biome, modeled as if it was built in about 1100 with no threat of invasion (which kind of means there's no need for a castle, but I've had fun building it anyway lol).

So far it has taken about 25 hours, all built by hand. Optimized for OptiFine. Looks best with the thing enabled that puts snow under walls and flowers. Now requires Quark and therefore Autoreglib. (Strictly speaking you only need to enable Carved Wood, More Stone Bricks, All the Chests, and Colored Beds, but I may use more of them in the future and I recommend the whole collection anyway, it's a great set of mods.)

Finished:

-Entry Hall
-Throne Room
-Hall of Glowstone
-Entry Towers
-Central courtyard
-Rear Towers with sitting rooms
-Grand Library
-Royal Museum
-Beacon Sitting Room (featuring disappearing-reappearing staircase!)
-Beacon
-Great Hall
-King and Queen's Tower, with sitting room, ballroom, and royal suite.
-Queen's Garden and patio
-Princes' and Princesses' Tower, with sitting room, two bedrooms, and two gardens.
-Greenhouse
-Courtier's suites, with two bedrooms, a large sitting room, a dining room, and a garden


In progress:

-Crypt


Future buildings:

-Secret Building~
-Kitchen
-Servants' quarters
-Dungeon
-Stables
Also probably a moat and drawbridge and outer wall but I may scrap those purely because I'm doing this all by hand and that's wayyy too much of a time commitment
