Watch as secrets revealed
BBC Wales's new TV series, My Secret Wales, started last night and if you watch online [fast forward through to 19 minutes] you get a revealing insight into the region's once most secret of places, Rhydymwyn's Valley Works - the former WWII chemical weapons factory.
Regulars to this website probably know much about the complex's fascinating history but presenter Sara Edwards took a tour with two former employees and a local historian to bring the empty complex back to life.
BTW, this week some of the uninspiring brick buildings were given protected status by Welsh preservation society CADW, owing to their historical importance.
Finally, a forthcoming episode of My Secret Wales comes from Denbign and there's a special screening at Denbigh Town Hall next Wednesday [11am] if you want to go along.
