A fine symmetrical building designed by William Deane Butler. It was originally built as a market house and the ground floor is arcaded.


Construction of The Market House began in 1844 and was completed in 1846 at the expense of Thomas B Leonard, it replaced and earlier 18 century market house . The outside of the building has some beautiful features including:

  • Carved stone plaque with Barrett Leonard Crest
  • A Cartouche and date stone
  • The cornice detailing
  • The cast iron tympanums with the TBL monogram

 The Market House had a cupola on the roof which unfortunately was removed during renovations in 1949 because the structure was considered dangerous. The upper floor served as a town hall and was also was used for public meetings. James Connolly 1868-1916 addressed a meeting of workers there in 1899 to select a workers representative to stand for election to the first Monaghan County Council. Percy French and his “Jarvey” Concert Co. held a concert here on 18th April 1890 and he appeared here again on April 22nd. 1897. Padraig Pearse another signatory of the 1916 Proclamation who was executed for his part in the 1916 Rising, delivered a lecture on the Gaelic League in this building in 1906, when a branch of the Gaelic League was formed in Clones.
The lower floor served as a working market house and had wrought iron gates were we now see these fine windows. The County Library set up headquarters here on the 1st April 1928 in the upstairs room. The Library then moved downstairs in 1966 and remained there until 2008

The Rebuild

Alastair Coey Architects was appointed in March 2012 by Monaghan County Council, with support from The Heritage Council to prepare a Conservation and Management Plan for Clones Market House. The Market House once underpinned the economic life of the town and its immediate hinterland. Disused for some years, the Client Brief required a full heritage assessment, in the form of a Conservation Management Plan, to sensitively guide the creative adaptation of the building while taking account of its heritage value.

The Council appointed Alastair Coey Architects to implement a number of policies contained within the plan, including implementation of urgent repairs to prevent further deterioration of fabric. This first phase of restoration work was carried out in 2013-14, involving roof restoration, replacement of lead tapered gutters, external re-rendering and repointing.
