Ruperra Motte, also known as Craig Ruperra Motte, (Welsh: Castell Breiniol, or Castell y Ddraenen) is a medieval motte and bailey castle in the community of Rudry close to the village of Draethen in the Caerphilly County Borough on the border with Newport in south west Wales.

[2][3] It is a Scheduled Monument within the Grade II listed Registered Historic Park & Garden, which also includes Ruperra Castle.

It is thought to have been part of the Norman invasion of south east Wales.

[1] Cadw, which works to protect the historic buildings and structures in Wales, says that "The site is of national importance as a multi-period defensive site, with well preserved remains of a hillfort, motte and 18th century garden features.

The site is well preserved and retains considerable archaeological potential"[1] The motte is a Scheduled Monument within the Grade II listed Registered Historic Park & Garden, which also includes Ruperra Castle.
