The 11th Lord Blayney also provided for the erection in Castleblayney of the current church buildings of the Catholic, Anglican and Presbyterian churches, being tolerant in religion if traditionalist in politics and strongly supportive of Empire and the Anglo-Irish 'Ascendancy'. He also had a Market House built, on to which the Courthouse was later superimposed in the quasi-centre of the town. It and the former Alms Houses (1876), which were interdenominationally managed, are the only civic buildings of any architectural merit in the town. As for older dwellings, a row of formerly Muckno Estate workers' cottages in Church St, possibly of Continental style, is of fine design and quality (apart from modern PVC windows). Some more substantial bourgeois houses in the square close to the Castle gates have Georgian echoes. The courthouse will soon undergo major refurbishment and restoration. About 40 structures and buildings are designated as being of 'regional or local importance'.
