"He (Richard) was removed from the dungeon _in the Tyrol_

The fortress, here represented to be in the _Tyrol_, is about 220
miles distant ("as the crow flies") from the nearest point in that
district, and is the Castle of Trifels, which still crowns the highest
of three rocky eminences (Treyfels = _Three Rocks_), which rise from
the mountain range of the Vosges, on the southern side of the town
of Annweiler. In proceeding from Landau to Zweibrücken (Deux-Ponts),
the traveller may see it on his left. The keep is still in good
preservation; and it was on account of the natural strength of its
position that the imperial crown-jewels were formerly preserved in it.

I am unable to refer at present to the MS. of Oxenedes (Cotton, Nero,
D 2), which appears to give the erroneous reading of _Tirualli_
for _Triualli_ or _Trivalli_; but Mr. Turner might have avoided the
mistake by comparing that MS. with the printed text of Hoveden, in
which Richard is represented as dating his letter "de Castello de
Triuellis, in quo detinebamur."
