Moy was laid out in the 1760s for the Volunteer Earl – the patriot and aesthete James Caulfeild, 1st Earl of Charlemont – opposite Charlemont Fort across the Blackwater. The formal rectangular market place, with lawns and horse-chestnut trees, was inspired by the square at Bosco Marengo in Lombardy, admired by the young earl during his grand tour of Europe. The houses lining the village square are mostly mid-18th century, though all four churches are later. Moy used to hold a great horse fair, held once a month and lasting a whole week. Moy had town commissioners under the Lighting of Towns Act, 1828 from 1844 until about 1865.

Moy features a cast-iron gate and screen set up in the 19th century to provide the grand entrance to the now-vanished Roxborough Castle. The richly modelled metalwork is thought by some to have been the work of the company of the celebrated Dublin iron-founder Richard Turner, best known for his conservatories in Dublin, Belfast and Kew Gardens. Turner designed a conservatory for the house c. 1850.
