This seems to be a section of a wall that marks the Southern boundary of the atrium and the Northern limit of a room which it forms in connection with North-Sourth wall 2276. The Western stone looks to have been intentionally cut, with a gap to the West of it and then another cut stone marking the Eastern end of 2260. The gap between these two appears to be a threshold between the atrium to the North and the room to the South. Due to the size of the Northern stone in 2276, the wall 2274 appears to have been put in after 2276, but possibly immediately after.
