The convents, nunneries, and other religious edifices, were converted into barracks and stables for the French army, and therefore exhibited nothing but naked walls, blackened and scorched by the fires made therein. The only place of worship that escaped the general wreck was the grand cathedral in the Plaza, which being a large unsightly pile, built without taste or uniformity, is not particularly ornamental to the town. Beyond the outskirts, are the ruins of an aqueduct, which bears upon its venerable front evidence sufficient of past respectability, and, though many centuries have rolled away since it was erected, several of its arches are still in a perfect state. On the road to Truxillo a new aqueduct has been built, which is not so light or well finished as the old one. The bridge across the Guadiana is remarkable for its great length and solidity; it has seventy-four arches, a great number of which are over a low marsh, on the banks of the river, dry in the summer months. The extent between each extremity is about eight-hundred yards. There are watch towers and seats along the battlements, and the whole structure, composed of a greyish stone, is well cemented, and seems formed to stand for as many more ages as it has already stood. Passing through Montijo and Talavera de la Real, we arrived on the 1st of November at Campo Mayor, in Portugal, where we found good quarters and civil inhabitants. The town is fortified, and is distant three leagues from Elvas, and three from Badajos. Campo Mayor was attacked and taken about a year before by the French, who afterwards gave it up as a situation unworthy of the garrison necessary to defend it. The houses are generally solid and well built, most of them had, however, been plundered and stripped of their interior workmanship and furniture, by their late visitors.--The streets are narrow, dirty, and ill-paved, but there are a number of respectable and well supplied shops. The market is good, and was well stocked with the abundant produce of the fertile country by which it is surrounded.
