At one end of the town on the slope of the hill stands the castle, and not far off in one of the streets is the town hall whose tower is too characteristic of the Alemtejo not to be noticed. The building is whitewashed and perfectly plain, with ordinary square windows. An outside stair leads to the upper story, and behind it rises the tower. It, like the building, is absolutely plain with semicircular openings near the top irregularly divided by a square pier. Close above these openings is a simple cornice on which stand rather high and narrow battlements; within them rises a short eight-sided spire, and at each corner a short round turret capped by a conical roof. The whole from top to bottom is plastered and whitewashed, and it is this glaring whiteness more than anything else which gives to the whole so Eastern a look. As to the castle, Haupt in his most interesting book, _Die Baukunst der Renaissance in Portugal_, says that, though he had never seen it, yet from descriptions of its plan he had come to the conclusion that it was the castle which, according to Vasari, was built by Andrea da Sansovino for Dom João II. Now it is well known that Sansovino was for nine years in Portugal and did much work there, but none of it can now be found except perhaps a beautiful Italian door in the palace at Cintra; Vasari also states that he did some work in the heavy and native style which the king liked. Is it possible that the castle of Alvito is one of his works in this native style? Vasari says that Sansovino built for Dom João a beautiful palace with four towers, and that part of it was decorated by him with paintings, and it was because Haupt believed that this castle was built round an arcaded court--a regular Italian feature, but one quite unknown in Portugal--that he thought it must be Sansovino's lost palace. As a matter of fact the court is not arcaded--there is only a row of rough plastered arches along one side; there are five and not four towers; there is no trace now of any fine painted decoration inside; and, in short, it is inconceivable that, even to please a king, an architect of the Italian renaissance could ever have designed such a building. The plan of the castle is roughly square with a round tower at three of the corners, and at the fourth or southern corner a much larger tower, rounded in front and projecting further from the walls. The main front is turned to the south-west, and on that side, as well as on the south-eastern, are the habitable parts of the castle. Farm buildings run along inside and outside the north-western, while the north-eastern side is bounded only by a high wall.
