Today was very hard work. Under Mark's supervision, Jay and Louise did a stone survey. Recordings were also done in Trench H with Harriet and Cat working on profile drawings. Jess was clearing Trench E today. Even I got down on site and had a go at clearing the trees with David inside the Lower House, to stop the overgrowth and hopefully kill it off. Culling the trees is very important to conserving the ruins as the roots destroy the building's foundations and roots and ivy grow through the mortar, so its pretty important to sort that issue! We also cleared the pathways to give better and safer access for the visitors at the open day on the 31st. The students were later visited by Dilwyn, an archivist who gave a talk on the history of the area and spoke of the various influential families and Welsh Houses of importance in the area. We later yet again tried to get inside Llanfihangel-y-Pennant to see the various artefacts but were unsuccessful.
