Been to the Lemp twice now and both times that north-east corner near the old wine cellar corridor was noticeably colder than anywhere else in that basement. Not just "old building cold" either, there's a measurable difference that doesn't line up with any obvious ventilation source that I could find.
Second visit I brought a basic IR thermometer and it was reading about 4-5 degrees lower than the surrounding area consistently. No draughts, no vents nearby, stone walls on two sides. I couldn't account for it through normal means.
What I find interesting is that corner specifically has the most documented activity reports going back decades. Whether thats coincidence or whether there's something to the idea that genuine anomalous cold spots correlate with high-activity locations I genuinely don't know, but it keeps coming up in multiple locations I've investigated.
Would be curious whether anyone else took any readings down there or if you just felt it subjectively. Both are worth recording honestly.
