Albornoz, in planning out the city walls, discovered that the part between Porta Cappuccini and Porta Perlici, where the hill descends towards the ravine, needed protection, so he built the strong fortress of San Antonio known as the Rocca Minore. It had a separate governor or Castellano, and though of minor importance, proved very efficient in repelling the attacks of besieging armies. The principal tower, though somewhat ruined, still looks very fine within its square enclosure of massive walls, now covered in places with heavy curtains of ivy, the home of countless birds. A pious Castellano in the fifteenth century left a fresco of the Crucifixion in the chapel with his portrait at the foot of the Cross, and as we look at it through the wooden gateway we are reminded of what otherwise from the deserted look of the place it is easy to forget, that people once lived and prayed at the Rocca as well as fought. [Illustration: LOOKING ACROSS THE ASSISAN ROOFS TOWARDS THE EAST] Cardinal Albornoz left the castle in charge of two Assisan captains, but from 1376 an uninterrupted line of governors received their salaries from whoever was master of Assisi at the time. Always chosen from other towns their privileges were quite distinct from those of the civil governors; but in the fifteenth century, owing to the weakness of the Priors, who failed to keep order among the lawless nobles of the town, their power increased. The Papal Legate then gave into the hands of the Castellano authority to issue edicts which the Priors had to obey, and in 1515 he was invested with the title of Podestà and Pretor of Assisi. But none of these governors seems to have misused their power over the town, probably because their rule was of too short a duration to carry out any ambitious scheme. And when the despot for the time being of Assisi came to stay, he took up his quarters in the castle, ruling governors, magistrates and people alike. In the time of the despot Broglia di Trino, we hear of the Priors wearily toiling up the steep ascent to place before him the acts they had passed in the municipal palace. He received them always in the open air, holding his councils either in the first enclosure by the well, or in the second by the castle keep, where many important conclusions were arrived at, and plans for the city's dominion laid out.
