Haras national de Lamballe, National stud farm and listed monument in Lamballe-Armor, France

The Haras National de Lamballe is a horse stud farm and listed monument in Lamballe-Armor, Brittany. A long gravel path runs between two symmetrical ranges of stone buildings: on the left, a low wing with a pale stone base and steep dark slate roof; on the right, a taller pavilion with a round-arched doorway with red doors and a round-arched window with shutters. Beyond the path stands a white building with a central pediment.

A temporary stallion depot housed 19 horses in Lamballe in 1780; the royal depot followed in autumn 1783, set up in a stable of the Saint-Martin barracks with eight stallions, two grooms and a master marshal. Abolished in 1790, it was revived by royal decree of 16 January 1825, closed again in 1834 with its four stallions sent to Langonnet, and took its definitive form in 1842, supplying stallions to owners of some 70,000 broodmares.

The stud gives its name to the Breton horse's Norfolk-Breton ancestry, bred here from Norfolk Trotter stallions imported from England. Each September it hosts the Mille Sabots, Brittany's largest equestrian festival, and it stages the national Breton horse show. A saddlery of honour and 22 horse-drawn vehicles are kept on site.

Visitors can join guided tours to see the stables and observe working activities firsthand. It is helpful to wear comfortable shoes and allow time to explore the different sections of the facility.

The stud's archives from 1864 to 2016 once measured 252 linear metres; after sorting finished in October 2018, only 49 metres were kept. The eleven stables built up to the early 20th century could house up to 350 stallions of all breeds.
