Nathan Morrow: Masonry Maintenance at Glenarm Castle: Challenges & Solutions.

We will be taking a virtual visit to Glenarm Castle where Nathan Morrow of The Rock Stone Masonry and team will demonstrate the repair of a stone pillar with sphere capital. He will also be discussing the challenges of maintenance priorities, good repairs and understanding defects. We will also hear from Adrian Morrow, Glenarm Estate Manager, about the history of Glenarm Castle and how they are bringing life to the estate.

‘The Rock’ Stone Masonry derives its name from Nathan Morrow’s family farm at the head of the nine glens of Antrim that is rich in heritage stone buildings and walls. From a young age Nathan has had a passion for heritage building and has always been drawn to the repair of them. Nathan served his apprenticeship with a very skilled and qualified stone mason, learning all aspects of masonry from walling to monumental masonry having carried out conservation repairs to some of the most prestigious listed buildings in Northern Ireland. Having established The Rock Stone Masonry in 2006 the business provides masonry contracts for the private and public sector carrying out restoration, hand carving and maintenance, as well as cladding and repair of bridges. Nathan has obtained a NVQ Lv3 in Heritage Skills with an Assessors Award in the field and an affiliate with the Institute of Historic Building Conservation (IHBC). Nathan is the Traditional Skills Education Officer for the IHBC NI branch and recently completed the Royal Society of Ulster Architects (RSUA) Conservation Course.

‘Carved at the Castle’

Over Nathan’s career he found that many traditional skills are slowly being dissolved by modern machinery. So, in 2020 he has collaborated with Glenarm Castle

Estate to provide a unique experience for people to learn various aspects of the ancient craft through workshops: ‘Carved at the Castle.’

These workshops will teach participants how to ‘V’ cut letters, lime point historical fabric and carry out maintenance and repairs throughout the estate alongside Nathan and the masons.

Specialising in the craft and developing peoples skills by using the ‘hands on’ traditional methods to keep these heritage skills alive.

Classes have been postponed due to Covid–19, however keep up to date here:
