There is a face peeping out from behind the flaking limewash.
I can smell the space before I can see it. It is dark and dank, and it takes a while for my eyes to adjust to the gloomy interior which reveals itself intermittently in swags of sunlight dropping in from behind the clouds.
In appreciating this it also demonstrates an innate sense of how buildings work, a relationship then between the seemly and seamlessness.
What I took from this tour was the commitment of the English Heritage project team to the smallest details.
