The Three Castles Grosmont Skenfrith & White

Three Castles: Grosmont, Skenfrith & White

The “Three Castles” refers to White Castle (see below), Skenfrith Castle (see second photo below), and Grosmont Castle (see the bottom photo below) in South Wales.

The trio of castles are grouped together as they were usually under the control of a single lord in the Monnow Valley in what is now present-day Monmouthshire in Wales.

These historic castles were built to secure the trade route through the valley and as a watch post against the Welsh.

History of the Castles

The castles were often granted as a set to a favourite lord by the ruling king of the time. Hubert de Burgh in the 13th century undertook a variety of improvements to the fortresses, upgrades that can still be seen today.
