Chadwicks Arch, Thomas Street, Dublin

Project: Monument Cleaning & Restoration.

  • Sympathetic Cleaning of entrance structure
  • Repair of Roman Stucco Cement
  • Refurbishment of stone arch

The work

The client contracted acol ltd to clean, repair and refurbish the iconic archway and entrance to their Thomas Street outlet in Dublin. The works included the repair of the Roman stucco cement that decorates the arch. Having weathered over the years, the lack of flashing at the top of the arch also meant that water was seeping into the main structure and had caused further damage.

Originally built in 1861, the monumental arch with imposing Doric columns was conceived as the entrance to Kelly’s, a well-known timber-merchants on the street until the mid-twentieth century.

acol is expert at the repair of Roman Stucco cement as borne out by our work on the facade of The Shelbourne Hotel. We are also expert at the sympathetic cleaning of all stone and brickwork.

The restoration work uncovered older lettering on the arch pointing to its past with the inscription: ‘City Saw Mills’ and ‘Timber and Slate Stores’.

The project was funded by Chadwick’s and supported by Dublin City Council's Shopfront Improvement Scheme for The Liberties and the Built Heritage Investment Scheme.
