Now, which way was north again?
You could use a compass. But I bet your question originated from you having too much trouble correcting a compass' magnetic heading to true North. Indeed, the more North you're located, the bigger that correction gets : too much trouble.
So I suggest the time-based method : quite a lot simpler !
The Bryncelyn Guesthouse's exit is located at 52°06'27.1"N 3°38'20.1"W, or in decimals : 52.107519N, 3.638926W.
In Greenwich, in the summer, the sun is right in the East at 6 o'clock UTC, so 7 o'clock UK local time. The sun moves 360° in 24 hours, so 15° per hour, so 1° every 4 minutes. So at Bruncelyn's exit, the sun is exactly East 3.638926 (in decimals) degrees later, which is exactly 3.638926 x 4 minutes, or 14,555704 minutes, or 14 minutes and 33 seconds later.
All this together means that at Bryncelyn's exit, the sun is exactly East at 7 hr 14 minutes and 33 seconds in the morning. But you asked where North was, not East, so there's some more to it ...
At that calculated time, look straight into the sun, and then look left in a perfect 90° angle : the direction then pointed at by your nose, thát's where true North is
(hope for a clear sky !)
