Architectural ensemble consisting of medieval housing, tower, passage and portico. The tower—which, together with the house, belonged to the cathedral deans—preserves the large portal and corresponds to the most ancient part, built in the 14th century. In the 15th century it was enlarged with the construction of the Gothic passageway to add the stables. One final extension that took place of 1550 consisted in the Renaissance portico in Canicouba street and a stage of the passageway over San Telmo street.
