Bodysgallen Hall is a manor house in Conwy county borough, north Wales, near the village of Llanrhos.

Bodysgallen was constructed as a tower house[citation needed] in the Middle Ages to serve as defensive support for nearby Conwy Castle.

According to tradition, the site of Bodysgallen was the 5th century AD stronghold of Cadwallon Lawhir, King of Gwynedd,[1] who had wide-ranging exploits as far as Northumberland.

According to the ancient record of Caernarvon,[2] Bod Caswallon (Bodysgallen) was one of the townships called Tre Welyog, meaning it was a unit of hereditary land (gwely) held in common by members of a wider family unit in medieval Wales,[3] which was often divided and subdivided among heirs to the fourth generation; with the passage of time some of the smaller landholders might be "bought out" and become tenants of a larger estate.

The 1620 block, built by Robert Wynn, finds its main entrance on the northwest exposure and has a 19th-century three storey gabled porch bay addition.

In the great hall, these arms display the shouldered form rendered in Plas Mawr, an Elizabethan townhouse in Conwy founded by a branch of the Wynns.

Richard Mostyn's son, Colonel (and governor) Roger Mostyn, is thought to have added the northwest wing to Bodysgallen, while Roger's son Dr Hugh Wynn, Prebendary of St Paul's Cathedral and Salisbury Cathedral,[6] is responsible for the northeast wing which had a date stone of 1730.

The core element of Bodysgallen Hall is the late 13th century watchtower, intended to assist in defense of Conwy Castle.

The square tower has a five-storey ascending anti-clockwise (non defensive) spiral staircase with one small room on each floor.

The tourist Richard Fenton noted in 1810 that Bodysgallen was "embosomed in woods of Noble growth, which are suffered to luxuriate their own way, without any fear of the axe".
