Except its far-famed castle, there is nothing very, particular to see in the town itself, which is not so picturesque as many we have visited.  A small river, the Seiont, passes close to it.  The whole town is surrounded by walks united to the castle.  The streets, though rather narrow, are laid out at right angles to each other, and are well paved and lighted.  We landed, and traversed the town.  We presently made our way to the castle.  The external walls are ten feet thick, are nearly entire, and enclose a space of three acres.  Within them is a gallery running right round, with loop-holes for the discharge of arrows.  We clambered up two or three of the towers, which had turrets on their summits; the most important of them is called the Eagle Tower.  We were shown a dark chamber, twelve feet by eight; and our guide declared that it was the room in which the first Prince of Wales was born; but, as papa observed, that could not have been the case, as the tower was not built at the time; besides, it was not at all the sort of place the queen would have selected as her bed-chamber; it was far more likely to have been a prison or guard-room.  The castle was built by Edward the First, soon after his conquest of Wales; and it was finished about the year 1293.  We all considered it the finest ruin we had yet seen.  About the time it was finished, the Welsh, led by Prince Madoc, attacked and captured the castle; when, according to the customs of the times, they put its garrison to death, and burnt the town.
