A castle on the terrace above the Mindel, built probably about 1100, and the lordship of the free noble family named from it.
The margraviate of Burgau, which later covers the country between the Iller and the Lech, does not exist yet: it is made only after 1212, when the counts of Berg take over Burgau and add the margrave's title inherited from Ronsberg.

- Family
- Bruno of Burgau is first recorded in 1147; the noble lords of Burgau are last mentioned in 1211, in the donation book of Wettenhausen abbey. Before April 1212 the counts of Berg (by Ehingen) took over the lordship, and from 1214-1216 Henry of Berg-Burgau is styled margrave, a title inherited through his mother Adelheid from the margraves of Ronsberg, whose male line ended in April 1212.

Where the sources disagree
- Do not back-project the margraviate of Burgau: the lordship passes to the counts of Berg only before April 1212 and the margrave's title appears in 1214-1216 (de.wikipedia Burgau).
Evidence: Dates of the family and of the transfer from de.wikipedia; the lordship's extent is not documented.
On the map: A castle district; most of the later margraviate is not this family's in 1200.
