Beaumaris is finely situated on the picturesque banks of the Menai, where it opens into the bay, and presents many attractions derived from its historical monuments, its natural advantages, and modern improvements. As the principal town in the island and county of Anglesea, it has long been a place of fashionable resort, and being at the same time the borough and market-town, it is a scene of considerable activity, cheerfulness, and animation. It is in general well built; particularly one street, the houses of which are large and commodious, and of superior design and execution. Of the original wall by which it was once enclosed, considerable portions still remain--sufficient to demonstrate, by their massive strength and durability, the iron features, and the no less iron policy of feudal times. The castle--erected by Edward the First, and now an imposing ruin close to the town--covers a large space of ground, but stands too low to produce that effect upon the spectator which it would have done had it, like so many of its cotemporaries, occupied an isolated and commanding position. It is surrounded by a deep fosse, with an entrance between two embattled walls on the east, with round and square towers. The gate opens into a spacious court, measuring fifty-seven yards by sixty, with four square towers, and an advanced-work on the east, called the Gunner's Walk. Within these was the keep--the body of the castle--nearly square, having a round tower at each angle, and another in the centre of each façade. The area forms an irregular octagon, of the dimensions above named. In the middle of the north side is the hall, twenty yards long by twelve broad, with two round towers, and several others about the inner and outer walls, built of a bluish stone intermixed with square stones, which produce a rather novel and pleasing effect. There appears to have been originally a communication round the whole buildings of the inner court by means of a gallery two yards broad, and which still remains nearly entire. In various recesses in different parts of the sides of this gallery are square apertures, which appear to have had trap-doors or openings into a dungeon beneath. The two eastern towers served also as dungeons, with a dark and narrow descent to each--sufficiently characteristic of the dark and despotic purposes to which they were applied. On the east side of this building are the remains of a very small chapel, arched and ribbed with painting and intersecting arches; also some Gothic pilasters and narrow lancet-headed windows, and various compartments, with closets constructed--after the manner of those times--in the centre of the massive walls.
