How did the manly men of Team Fortress appear at a tenth century battlement? Simple. The Soldier angered a magician.

DeGroot Keep is an official Medieval Mode Attack/Defend Control Point map that was released with the Australian Christmas update on December 17, 2010 Patch. It is currently the only official map designed for this game mode.

DeGroot Keep is a fairly small Attack/Defend map, featuring DeGroot Keep, the namesake of the map. The buildings and fortifications on the map are medieval-style, and Health pickups inside the keep appear as medieval-style roast meat. DeGroot Keep is supposedly a 10th century manor, but there are several hints scattered throughout the map that suggest that the team is merely in some kind of medieval simulation.

DeGroot Keep has three Control Points. Point A and Point B are located outside of the keep, and Point C is located in the courtyard of the keep. The only entrance into the keep is the castle gate, initially closed and impassible. until BLU captures Points A and B. This forces RED to mount a defense from the top of the castle. RED can fire projectiles from above or leap off the walls to engage BLU directly.

After BLU captures Points A and B, the castle gate will rise and allow access to Point C. BLU is given 60 seconds to capture Point C. After the 60 seconds expires and capture progress is entirely reverted, the gate will close again. BLU then needs to recapture Points A and B before another attempt can be made on Point C. This repeats until the round ends.

Players can shoot projectiles through the grills of the castle gate or arrow slits in the towers. Braziers and torches located near the team bases can be used to set arrows on fire for additional damage.


Overview of the map. (Large file)

DeGroot Keep is a small single stage map containing three control points and two bases in a similar fashion to Gravel Pit and Junction.


  • BLU Camp: The BLU team's spawn is a small camp surrounded by palisade walls. Behind the camp is an archery range and a path leading into the forest behind it, both inaccessible.
  • Battlefield: Between DeGroot Keep and the BLU camp is the battlefield where the majority of combat takes place. The battlefield is a large hill, with Degroot Keep and the BLU camp on lower ground. A tree, fence, and large rock at the brow of the hill can be used as cover against fired projectile weapons from RED players or cover for BLU players firing them.
  • Braziers: Along the hill are two flaming braziers which can be used to light Sniper arrows on fire.
  • Rock: A large rock at the top of the hill can be charged at by Demomen using the Chargin' Targe, Splendid Screen, or Tide Turner to propel them to the top of Degroot Keep, bypassing the gate.

Outside Capture Points

  • Town (Point A): Point A is located to the left of DeGroot Keep, between the keep wall and a few decorational buildings. A hole in the castle wall allows RED to jump onto the point or attack from atop the keep.
  • Cliffside (Point B): Point B is located to the right of the keep, between the keep wall and the cliff-edge of the map. RED can also drop down onto this point from the castle wall.

DeGroot Keep

  • Courtyard (Point C): The courtyard is the main area of the castle located between RED's spawn and the gate entrance. The Control Point is located in a enclosed area of the courtyard. There are a set of stairs which lead to the castle halls.
  • Gate: The main entrance, and only entrance to the castle for most players, is a large metal gate located at the center of the castle walls. If the gate closes, any players standing directly beneath the gate will be crushed and die.
  • Castle Halls: The halls are located below the battlements but above the courtyard and RED's spawn. They can be accessed through staircases in the courtyard and the spawn room. The hall also contains the only stairs to the battlements.
  • Battlements: The top floor of the castle. Players standing here have a clear view of the battlefield. On both sides of the battlements, a break in the walls allows castle defenders to drop directly onto Control Points A and B. The battlements also has braziers which can be used to light Sniper arrows on fire. The height advantage makes the battlements an ideal spot for users of projectile weapons to fire from. A Demoman with any shield can access this area by Rampsliding up the big rock on the top of the battlefield.

Update history

December 17, 2010 Patch (Australian Christmas)

  • Added DeGroot Keep to the game.

December 22, 2010 Patch

  • Improved performance on DeGroot Keep.

January 3, 2011 Patch

  • Updated DeGroot Keep to fix a problem with missing models.

January 19, 2011 Patch

  • Added a timer to indicate how much time is left before the gate closes in DeGroot Keep.
  • [Undocumented] Fixed players being able to clip through the barrels on the shelves above the BLU spawn area in DeGroot Keep.


  • One of the gates in BLU's spawn area can become stuck and not open at the beginning of the round.
    • It's possible to block gates with the Sandman's ball, as seen here.
  • The keep gate may improperly appear open or closed. Players will still interact with it as they should, being unable to pass if it should be closed or passing through if it should be open.
  • Players can stand on the ledge behind a tree on the cliffside.
  • A Scout can get stuck in the roof of control point C using Double Jump. However, the game will count the Scout as standing on the point, so BLU Scouts will still cap the point and RED Scouts will still defend the point. This is shown here.
  • If RED wins, the MVP list says that they captured all the points and displays the names of people who captured the last point for BLU under "Winning capture".
  • It is possible with the Ullapool Caber and the B.A.S.E. Jumper, to get outside the hurtbox of the cliff and back.


The DeGroot family portrait.
  • Despite the Demoman's Scottish origins, DeGroot or de Groot is a surname of Dutch origin meaning "the big" or "the great".
  • The DeGroot family coat of arms' motto is "Regionem Caecorum", which is Latin for "country of the blind".
  • According to the official Australian Christmas event page, the map is supposed to be set during the 10th century. However, a number of anachronisms can be seen, such as various computer terminals hidden across the map, tiretracks leading up to BLU camp as well as an unused ticket booth model within the game files, suggesting that the castle is, in fact, nothing more than a tourist attraction.
  • The bagpipe music heard whenever the castle door opens is a reuse of the Day of Defeat anthem, used when a round is won by the British team.
  • There is an unused scroll model in the game files. Its intended use is unknown besides that it was to be a pickup.
