Counter-Strike Wiki

Cobblestone (de_cbble), formerly known as Cobble, is a bomb defusal map featured in the Counter-Strike series. It was added to Counter-Strike: Global Offensive in the Winter Offensive update alongside the map Overpass. It is currently in Defusal Group Sigma and is available for Casual matchmaking, Deathmatch and the B bombsite is used for Wingman.


Cobblestone is a large-sized map, and had quite significant vertical combat in its earlier iterations. In earlier versions, it is fairly easy to take fall damage due to the high height of many of the map's drops. Bots in early versions of the game will also occasionally fall to their deaths. Additionally, this map is open, making snipers very useful.

Bombsite A is located right next to the Counter-Terrorist spawn, and bombsite B is located around a large statue. Terrorists spawn in lower area with a sniper tower nearby, a tunnel to bombsite A and stairs to bombsite B. Path to bombsite A leads to a very open area leading either to A long, underpass or to bombsite B via a connector. Path to B leads to tunnels with B long and a drop.

Wingman version of the map has only bombsite B, with Terrorists spawning in tunnels and Counter-Terrorists spawning in the connector between A and B bombsites.



Official Description[]

Counter-Terrorists: Prevent terrorists from bombing Lord William's country farmhouse. He has been the target of assassination in light of recent government proposals.

Terrorists: The Terrorist carrying the C4 must place the bomb at one of the two bomb sites around the map, thereby killing Lord William and severely damaging his home.

Development History[]


The map was designed by David Johnston after completing Dust. He had a large castle for a map in mind, and created cs_cstle (Castle). Chris Ashton supplied Johnston with the necessary textures. However, the map was rejected due to gameplay issues.[1] Johnston decided to restart the development and quickly made a new castle-themed map, which became de_cbble (Cobble), and was designed around similar principles as Dust.[2][3]

It was first introduced in BETA 6.5, and saw a few more revisions before its final release to make it more competitively viable.[3]

Cbble remained mostly unchanged in both the Xbox edition and Condition Zero, aside from texture and lighting updates.

Counter-Strike: Source[]

To accommodate with the new Source Engine, the map had graphical and textural tweaks though the integrity of Cbble remained unchanged.

Counter-Strike: Global Offensive[]

Cobblestone was re-introduced as part of the December 18, 2013 update. Valve performed a major overhaul to the map, graphically and strategically. Nearly all of the crates were removed and replaced with more realistic props. The hallways had become filled with museum artifacts instead of crates, similar to Piranesi. Additionally, the map is littered with some construction equipment and Medieval props, completing the transition from just an old medieval castle in the previous games to a historical museum and tourist attraction somewhere in France.

The map was significantly updated over many updates. Some sniper positions were removed, while new connectors were added.

On October 23, 2018 update was added a halloween version of the map with some layout changes.

On March 19, 2019 update, Cobblestone has been removed from Competitive Matchmaking. This was due to it's low popularity and complaints after the Halloween Update.

  • According to the official description of de_chateau, the Terrorists were able to successfully bomb Lord William's country farmhouse (Cobble). However, Lord William survived, and was rebuilding his summer investment (Chateau).

Counter-Strike : Condition Zero

  • In Tour of Dutys mode, the textures in the preview image of this map differ from the actual map.
  • In Conidtion Zero's game source directory, its CZ remake still specifies the 1.6 overview file (de_cbble.bmp) instead of the corresponding CZ remake's overview file (de_cbble_cz.bmp), for reasons that are not known.
Global Offensive
  • In Guardian mode, the map's only hostage is named "Lord William."
  • A sign near the door handle on the toilets changes color when a person is occupying the toilet.
  • The pre-rendered shadows on the map were mismatched in directions to the live-rendered shadows on the map.
  • A symbol is hidden in a box near T main entrance to Bombsite B, visible by noclipping into it.
  • In the Cobblestone collection, the CZ75-Auto | Chalice is a reference to the Chalice in the movie Indiana Jones: The Last Crusade, as its flavor text is "Choose wisely".
  • Assets for old remake of de_cbble can be found within the game files. These files suggest that this cancelled de_cbble remake was set around a medieval fair inside a castle instead of the castle undergoing renovations. The flagpole models are animated.
