For those of who that have played Half Life 2, this is a replica of the citadel that I made but a Minecraft version of it. First of all, I know there are ones others have made but this is mine. It stretches from bedrock all the way up to the sky limit, so it's quite large. There's also a few easter eggs hidden, so keep an eye out for them, enjoy! (As a side note, this is my first time uploading anything to planetminecraft)
