Cobblestone ( ), formerly known as de_cbble Cbble and also known as Cobble, is a bomb defusal map featured in the . It was added to Counter-Strike series in the Counter-Strike: Global Offensive Winter Offensive update alongside the map Overpass.
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.
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. 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.  
The map was first introduced in BETA 6.5, and has seen a few more revisions before its final release to make it more competitively viable.
Not much has changed in Cbble, other than the lightning.
To accommodate with the new Source Engine, the map had graphical and textural tweaks though the integrity of Cbble remained unchanged.
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.

Cobblestone was originally named "de_cbble" instead of "de_cobble" in honor of the old, eight character restriction.
 According to the official description of de_chateau, the Terrorists were able to successfully bomb Lord William's country farmhouse (Cobble). However, it appears Lord William survived, and was rebuilding his summer investment (Chateau).
The description means this is the only time when the Terrorists have ever canonically bombed a map.
Despite the description, Lord William does not appear on the map, nor does he appear in any other part of the Counter-Strike series. However, Lord William is the focus of two missions in both of the Operation Bloodhound campaigns.
Due to the verticality of this map, it is fairly easy to take fall damage. Bots in early versions of the game will also occasionally fall to their deaths.
In , when Counter-Strike: Condition Zero bots plant the bomb at bombsite A, the bots usually plant it near a crate, potentially clipping inside the crate, rendering it un-defusable.
In Global Offensive's Guardian mode, the map's only hostage is named "Lord William."
In Global Offensive, a sign near the door handle on the toilets changes color when a person is occupying the toilet.
In Global Offensive, the pre-rendered shadows on the map were mismatched in directions to the live-rendered shadows on the map.
