As the title says, a medieval style texture pack for Minecraft. Bal introduced me to it (and gently encouraged me to use it) and now I'm using it most of the time, unless I specifically need to revert to the default.
If you don't use SpoutCraft, you will need to patch your client with this patcher:http://www.minecraftforum.net/topic/232701-124-125update-328-mcpatcher-hd-fix-235-01/
(Scroll down to the bottom of the post and pick one of the two download links.)
Instructions for patching are included in the post, and it's very straight-forward.
After that, go to http://massivecraft.com/media
and download the first file there - the medieval pack. Open the folder it is stored in - it will be a .zip file, do NOT extract it from this format. With this folder open, load up Minecraft and go to Textures>Open Textures Folder. This will open a new window. Now copy the texture pack from the download folder to the textures folder, and close it and the pack is installed, ready for use. Click on it, and click Done
Now log into the server as normal, and enjoy a rather pleasant, medieval look to minecraft
