Parkmill once lay within a Medieval deer park, Parc le Breos, which was established in the 1221-32 CE by John de Braose, Marcher Lord of Gower as an enclosed area of about 2,000 acres (800 hectares).
The park is now mainly farmland and has a 19th-century Hunting Lodge, which is now an hotel and pony trekking (horse riding) centre called Parc le Breos, built about one mile (1.6 km) east north east of Parkmill[REF][REF][REF] .
