One from a visit on Monday to Beeston Castle (which is a superb setting, great views of the Cheshire plain).
It's to the left (as you look) of the gatehouse entry.
A replica round house is being built in the grounds, no power tools allowed. Seeing the saw horses and things is great. The roof is going on in June and the wattle and daub after that. Should be finished by October.
And one I found when I went to vote yesterday, on my village hall. I have looked previously, but it's quite well hidden. There was a sign at the entry to the polling station saying "no social media posts allowed". I wonder if CC counts?
