Where the facts come from
Every factual claim on this site links to its source. This is the full list.
How we checked
Each fact was written alongside its source. Our build script stores the source text and, for every fact, checks that the key words and figures really appear in it. 134 of 134 checks passed when this site was last built (checked 30 Oct 2026). Where we couldn’t read a source, we left the claim out. We quote short phrases only, and never reproduce museum images or the Bayeux Tapestry.
Figures that change
Opening times, entry and visitor notices can change. Facts like these are marked “checked 30 Oct 2026”.
What we leave out
This is a site about the history of motte-and-bailey castles and about spotting and visiting them. It isn’t a visitor guide with live opening times or access advice: check with the site you’re visiting. Where one organisation’s own pages disagree with each other, we show both rather than choose silently.

When sources disagree
Where sources give different figures, we show all of them, with links, and say how we handle it.
Was the bailey beside the motte, or all round it?
- English Heritage says motte-and-bailey designs were very common: a mound topped by a wooden tower, with a defended enclosure, the bailey, alongside. English Heritage: Castles Through Time
- The National Archives describes the bailey as a large ditch-and-bank enclosure that surrounded the motte. The National Archives: Medieval castles (education)
- English Heritage’s castle-spotting guide also calls the bailey the outer fenced enclosure surrounding the motte. English Heritage blog: How to spot a castle hiding in plain sight
- Britannica Kids puts the bailey at the base of the motte. Britannica Kids (Students): Castle
- At Totnes the bailey is a larger enclosure on level ground below the motte. English Heritage: History of Totnes Castle
- At Duffus the bailey lies to the east of the motte, across a broad, deep ditch. Historic Environment Scotland: Duffus Castle Statement of Significance
How we handle it: English Heritage’s Castles Through Time says the bailey was alongside the motte; The National Archives and English Heritage’s castle-spotting guide say it surrounded the motte; Britannica Kids puts it at the base. Real castles varied: at Totnes and Duffus the bailey lies on one side. Our drawings show the bailey beside the motte, as at Totnes and Duffus.
When was Totnes Castle founded?
- English Heritage’s Totnes history says the castle was founded around 1087, inside an Anglo-Saxon town, by a follower of William I. English Heritage: History of Totnes Castle
- Its Norman Castles page also says Totnes was founded around 1087. English Heritage: Norman Castles
- English Heritage’s castle-spotting guide says Totnes Castle was raised in 1068. English Heritage blog: How to spot a castle hiding in plain sight
How we handle it: Two English Heritage pages say around 1087; its castle-spotting guide says 1068. We give around 1087 on our timeline (from the Totnes history) and show 1068 here.
How old is the mound at Skipsea?
- English Heritage’s Norman Castles page says an Iron Age mound was made into the motte at Skipsea, a castle from before 1086. English Heritage: Norman Castles
- Its castle-spotting guide says recent evidence shows the Skipsea mound was first built in the Late Stone Age, about three and a half thousand years earlier. English Heritage blog: How to spot a castle hiding in plain sight
How we handle it: English Heritage’s Norman Castles page says an Iron Age mound was reused; its castle-spotting guide says recent evidence shows the mound was first built in the Late Stone Age. Both agree the Normans reused an older mound as a motte. We give both.
When was the stone keep at Duffus built?
- In about 1270 Duffus passed to Sir Reginald Cheyne the Elder, who probably built the square stone keep on the motte. Historic Environment Scotland: Duffus Castle, history and stories
- Historic Environment Scotland’s visitor page says the stone castle seen today was built in the 1300s, replacing a timber stronghold. Historic Environment Scotland: Duffus Castle
- Its Statement of Significance says the ruined stone keep and the bailey’s curtain wall are most likely early 14th century. Historic Environment Scotland: Duffus Castle Statement of Significance
How we handle it: Historic Environment Scotland’s history says Sir Reginald Cheyne probably built it after about 1270; its visitor page says the stone castle was built in the 1300s; its Statement of Significance says most likely early 14th century. We say late 1200s or early 1300s, and show all three.
