Henllys Hall, Beaumaris, Anglesey. Evaluation Report

An archaeological evaluation was carried out by Lancaster University Archaeological
Unit (LUAU), on behalf of John Moore and Partners, at Henllys Hall, Beaumaris,
Anglesey (NGR SH 6005 7765), in June and July 2001, in advance of a proposed holiday
apartment development. The hall is thought to stand on the site of a llys or court of the
thirteenth century princes of Gwynedd. The work followed an earlier archaeological
assessment of the site, combining a desk-based study with a walk-over survey, also
conducted by LUAU. The present project involved the detailed landscape survey of three
features identified during the assessment, the fabric survey of a relict doorway within the
basement of the hall, and also a programme of evaluation trenching to examine the
grounds of the hall.
