It was good to see the oak grove from the arboretum at Dyffryn Gardens standing in for Alvarr's camp in this week's episode. (I didn't catch the name of the fictional forest. Did anyone else...?)
I will do a proper post soon, but in the meantime, thought I'd add another couple of photos - including the hollow oak in which Merlin sheltered from arrows!
And in the meantime... I am loving this big dramatic build towards the end of the season, but I am already in mourning with only two episodes to go!
