It was an entrance to the grounds of that building, which seems to have been a pair of big oak doors which were shut when I went past. Apparently you could get through them earlier.
As I ran past on the way to 11, I tested the doors to see if they were openable - they weren't so I took the northern route. Trouble was, I was so focused on that, I forgot to punch at 10!

On control 17: I don't see this as requiring a degree in control description reading. The description was straightforward and precise. It just needed to be read accurately, something I failed to do in the sprint final, when I forgot to check in which angle no. 15 on course B (M50) was hung, losing about 15 seconds and several places hesitating with the control in sight but still uncertain which side of the fence it was hung. That's the name of the game to me - I know that some prefer the more traditional approach to control descriptions, but personally I enjoy, indeed prefer, the extra demands that this places on the competitor.
BTW, I do agree about ambiguity in descriptions, but in both cases the descriptions were pretty unambiguous.
