Mynydd Ty Talwyn Ancient Farms is a medieval house platform located in Wales, protected as a scheduled monument by Cadw under reference GM092. The site occupies ground underlain by the South Wales Upper Coal Measures Formation, a geological sequence of Westphalian age comprising mudstone, siltstone, sandstone, coal, ironstone and ferricrete. This varied bedrock would have influenced both settlement location and the availability of building materials throughout the medieval period.
The house platform represents a type of settlement common across upland Wales during the medieval era, where communities adapted their dwellings to challenging terrain and variable soil conditions. Platforms such as this were typically constructed by terracing into hillsides, creating level ground suitable for timber or stone structures. The underlying Coal Measures geology would have affected drainage and soil stability, shaping how inhabitants organised their domestic spaces.
The monument survives as an earthwork feature within the modern landscape, preserving evidence of medieval agricultural settlement patterns in this region. Its archaeological value lies in the potential to understand how medieval Welsh communities utilised upland terrain and exploited local resources. The site remains under statutory protection, recognising its significance as a record of settlement and land use during the medieval period.
