Krosno stands where the Bóbr meets the Oder, an old Polish border castle (Thietmar names it in Henry II's war of 1005).
It faces Lower Lusatia across the Bóbr and the Neisse; later it is Henry the Bearded's favourite residence and the place of his death (1238).
Who he is

- Title
- Castellan of Krosno
- Confidence

Henry the Bearded's foundation charter for Trzebnica (act of 28 June 1202, written down in 1203 after 22 January; Schlesisches Urkundenbuch I, via dokumentyslaska.pl) names the castellans of Henry's first year. Whether the same man held the castle under Bolesław on 1 January 1200 is not pinned.

Bolesław I the Tall, duke of Silesia
What it holds
- The castle of Krosno at the Bóbr mouth
- The Oder and Bóbr crossings

How it was acquired
Appointed by the duke at his pleasure; the castellan is not a hereditary lord.
How things stand that morning
Held for Bolesław by his castellan (not pinned). Across the Neisse is Margrave Conrad II's Lower Lusatia (Gubin).
Threats

Where the sources disagree
Evidence: The castle and its district are attested; the castellan's name for 1200 and the exact bounds of the district are not.
On the map: The district is drawn from its head castle and a few places near its later edges; its 1200 bounds are not documented.

- Chronicle of the Poles, by Master Vincent (Wincenty Kadłubek), Wincenty Kadłubek (about 1190 to 1208). Book 4 is a contemporary's account of the fight for the senior throne of Kraków. Read online
- The annals of the Kraków chapter and the other Polish annals (kept from the 11th century; the Kraków chapter annals continued to 1266). Short dated entries that fix the chronology Kadłubek blurs: the deaths of dukes and bishops, Mieszko the Old's captures of Kraków, Prussian raids on Masovia, church consecrations. Read online
