Built on the hill clos­est to the cap­i­tal in the 9th cen­tu­ry. A muse­um has been opened with­in its walls. The exhibits show the fur­nish­ings and inte­ri­or of the rooms, which were in fash­ion at that time, and inter­est­ing house­hold items of the Urgel­sky fam­i­ly are also kept here. A pic­turesque panora­ma opens up from the height of the watch­tow­er.
