I was finally able to contact one of the original creators of this map, Rigolo, and asked him to consider uploading v15.0 on the original post, however he declined. His exact response was:

"I have no problem with other people downloading the map and modifying it, however we agreed with the other builders years ago that the project on planet minecraft would stay as we made it, even if it is not complete. So I cannot replace the file nor present another version as the last one."

So all I can do is post v15.0 in a new project.

Allow me to present: Imperial City (v15.0)

I am a long-time Minecraft player and have always considered the Imperial City project to be perhaps the most amazing and impressive Minecraft creation of all time. However, I became a little perturbed that it was never updated or completed by the original builders. So approximately two years ago I began updating the map myself.

Now, I didn’t want to mess with any of the player-made creations, but I did want to “clean-up” all the naturally generated terrain surrounding the city to make it look nice and neat and to reduce unnecessary lag. So I got to work!

The first thing I did was create a new customised super-flat world (with the parameters described below) and cut and paste the entire city into it (don’t worry, I made sure to get it all. ;)

Then I set about using WorldEdit to select regions of naturally-generated terrain and either deleted it, or replaced it with plain stone if it was below Y=20. The above-ground work was pretty simple, however the bulk of the time spent on this MONUMENTAL undertaking was spent very carefully hollowing out all the underground area and then filling it back in with plain stone. This took me almost two years (I’d estimate 1000+ hours) (and no, I had no idea when I began this project that it would take me nearly this long, I thought a couple of months tops, boy was I wrong)!

Now, I do have OCD, so let me assure you that I did this work properly, and did not damage any of the city while doing it. I must have switched back and forth between creative mode and spectator mode 10,000 times while doing this to ensure I was selecting the correct spaces!!! lol

Due to the nature of how Minecraft saves worlds, which is in large regions of 32 x 32 chunks, I decided to set the city limits at 1,024 blocks from the (0, 0) origin point. This enabled the entire map to be saved as 16 region files. I centered the city around the (0, 0) origin point, using the central square city block as the de-facto center of the city, and the 2 x 2 block “The flame of the unknown soldier” monument as the origin point. I also set aside a one-chunk wide area surrounding the city as a potential 'city-wall' area. This wall would occupy the 64th chunk from the origin point (and the outermost chunks of those 16 region files). However, I did not want to take it upon myself to build this wall, as I was unsure if I would get the imperial style just right, so I leave this up to others to design.

Now, choosing to have a city-limit, required me to relocate a handful of structures that had originally been built rather far away from the rest of the city. So I (again, carefully) moved them directly inwards (either along the X or Z axis) towards the city, so that they would be completely within the city limits (within the 63 chunk radius of the city, ignoring the 'city-wall' chunk). The structures that I had to do this to include:
  • The previously underground structure on the Southern edge of the map behind the Cathedral.
  • The circular garden beside the Cathedral on the Western edge of the map.
  • The two large ships on the Western edge of the map.
  • The large tower beside the Winter Palace on the Western edge of the map.
  • The large building that contains the giant cannon (and the dome-top building adjoining it) behind the military district on the Northern edge of the map.
  • The observatory building behind the Stadium on the Northern edge of the map.
  • The rear section of the “Palais Episcapal” on the Eastern edge of the map.
  • And finally, the flying blimp on the Eastern edge of the map.

I left some signposts in front of these structures explaining that they have been moved inwards.

Since I made the city centered around the origin point, I thought I’d also relocate the World Spawn Point there as well (as opposed to in front of the Museum). I placed an enormous map wall there as well so you can see a birds-eye view of the city layout in all its glory, but if this causes too much lag for your graphics card, then I suggest just removing it.

I replaced the TNT in the smaller pirate ship with sponge, so it wouldn’t accidentally detonate. 😊

I had to move the redstone structure at this location: X:-787, Z:-178 approx. 33 blocks to the West so that it wouldn’t overhang the diagonal riverbank. I also repaired the redstone inside.

I completely terraformed the 'naturally-generated' terrain of the large archway opposite the lighthouse. I made the archway out of solid stone (with some grass on the top) and I left off the 'player-made' custom trees because they no longer connected to the re-made terrain.

I cleaned up the interior of the 'Arc de Triomphe' at spawn.

I manually fixed all the stair blocks that hadn't correctly rotated in 'The Winter Palace' when it had been built.

I did some basic ‘tidying up’ of the underside of The Stadium (X: 478 , Z: -617) and the underside of The Baroque Church (X: 355 , Z: -170). And since I did not know if the original creators of these buildings intended them to be hollow and filled with rooms, or solid and built into the ground, I left their underside empty and covered in torches to prevent mob spawning.

I also replaced levers that were powering redstone lamps, with redstone blocks in basically every structure in the city. Although I usually only did this if the redstone blocks would have been hidden from sight in walls. This is because redstone blocks have no ‘block state’ that would need to be calculated every time a chunk is loaded that contains them. As opposed to levers, that have three ‘block states’. It is my hope that doing this reduces lag while travelling around the map loading in new chunks (instead of minecraft having to calculate the block states of thousands of levers all over the city, it just has to load in the redstone blocks).

I had to drop the level of the river surface in front of The Summer Palace by two blocks to match the level of the docks in that section of the river. So I built some simple-looking water levies underneath two of the bridges.

I had to decide how to make the river curve in two locations; at the corner of The Winter Palace, and at the opposite corner of the main island. I tried a few different curves, but eventually just settled on simple diagonal shorelines, which you can always alter if you prefer.

Customised, Super-flat World Settings:

World Name: Imperial City v15.0

saved in: Imperial City v15_0

Version: 1.12
(I chose not to update the Minecraft version, just in-case others wish to use WorldEdit or MCEdit to make further alterations.)

Game Mode: Creative

Seed: 1

Generate Structures: OFF

Allow Cheats: ON

Bonus Chest: OFF

World Type: Superflat (customized)


  • 3 = version number
  • 1 x layer of bedrock
  • 18 x layers of stone
  • 1 x layer of grass
  • 1 = biome ID (Plains)

There are no “naturally generated” structures in this world (ie: villages, mineshafts, strongholds, biome-specific structures, dungeons, decorations, water-lakes, lava-lakes, ocean-monuments, ect.). They cause unnecessary lag.

Ground level therefore equals 20 (Y=20).

This gives enough height space to fit in all the tallest buildings (like the Cathedral).

Water level equals 13 (Y=13).

River Bottom equals 6 (Y=6).

Here are some ideas I had for the next stage of city development:

  • Complete the ten pylons for the southern bridge that crosses the small island. They don't currently reach to the river bottom.
  • If updating the map to 1.13, you may want to manually water-log all the underwater fence posts throughout the river system.
  • Before building the square city wall, consider making the city into a circular shape, with a circular wall. Or an octagonal shape, with an octagonal wall.
  • The entire map was set with the default biome of 1 (Plains). So consider changing the biome of the river system and turning on 'Mob Spawning', so that aquatic life can start to spawn.
  • If updating the version to 1.13, consider placing lots of sea pickles on the river bottom to light it all up.
  • If updating the version to 1.14, consider replacing all the underground street lights, with above-ground street lanterns on posts.
  • Connect and complete the underground subway system. Maybe an above-ground monorail system also?
  • Start filling in the corners of the map.
  • Maybe create extra river 'loops' around the northern section of buildings and around the southern section of buildings, creating three large islands.
  • Encase the entire city in an enormous glass dome, and terraform the outside to make it look like a post-apocalyptic lava world.
  • Hot-air balloons, blimps, zeppelins all over the city.
  • Create custom mountains in the corners, so that the city looks like it lies in a vally.
  • Create an adventure map/scavenger hunt with clues that lead players all over the city.
  • Pirate ships. Lots, lots more pirate ships.

If you’re curious as to the differences between v15.0 & v14.1, you can always download both maps, drink a night-vision potion, slip into 'Spectator' mode, and start flying around underground. 😊

The world file size is also significantly reduced in v15.0 compared to v14.1. Without all the messy and redundant terrain below and around the city, the file size has been reduced from approx. 210 MB (v14.1), to approx. 80 MB (v15.0) which would be an approx. decrease of 62%.

I have been contacting some prominant Youtubers and pitching them the idea of producing a new, great cinematic showcase video of the updated city, so if you're interested in doing this (or know someone that might be), please let me know.

That’s all from me. Major props to the original creators of this incredible map, Rigolo & Comeon. Please feel free to comment below and I hope you all enjoy the work I put into this project. 😊



First 151 downloads – incomplete redstone lamps, map wall and redstone build.

First 236 downloads – lacking underground structure behind Cathedral.

First 246 downloads – pre-terraformed Archway & messy Arc de Triomphe.

First 268 downloads – incorrect orientation of upside down stone brick stair blocks on Winter Palace, uneven water flow in fountains in front of cathedral, chest with crap in large building next to spawn.

No, sorry. I've moved on to other projects.
Perhaps you could contact some of the other enthusiasts in this comments section and start a team.
I provided some ideas for the next stage of city development if you need some inspiration.
I'd love to see what you, or someone else comes up with. ;)
Thanks for the offer & the diamond, though! :)

Nice job! It would be fantastic if this could actually be completed someday. What you've done here might provide some drive for good builders to help complete this. Good work.

Impressive ! Thank you for bringing this amazing map back. What do you think is the future of this city now ? Are you going to gather a team of builders to take over and finish it? It would be a shame to see such a great project go unifnished forever. I'm not nearly as talented as the original builders of this map but if I can help with anything I would be glad to try working on this project. It deserves to be complete.

Anyway, thank you for your hard work, and have an awesome day ! (And please forgive my poor English, I'm French)
