Beaumaris is one of the great castles of North Wales built by the English monarch Edward I, to stamp his authority on the Welsh. In the 13th century, its concentric walls within walls design was the state of the art in military technology. It is said to be the most technically perfect of all Welsh castles. It was the last of the great castles to be undertaken by the King’s designer Master St George, and remains in a relatively good state of preservation.
Beaumaris Castle is situated near the coast, and at sea level. It looks unexpectedly squat, partly because of its low siting, but mainly because the towers were never completed to the originally planned height (the King ran out of money). It is surrounded by a moat, an outer defensive wall, and an outer bailey, before one reaches the main walls and towers. Inside, the inner bailey looks big enough for a football pitch. The inner walls are honeycombed with defensive passages, and the inner and outer walls have walkways on top, some still accessible. You can spend a couple of hours exploring it all.
Well worth a visit if you like castles. Pay car parking is available nearby.
Also in Beaumaris town, the old gaol is worth a visit, as is the old courthouse. Together they vividly recall the harshness of Victorian justice. In the jail, inmates were properly fed and given medical attention as required, (which was much better than most of them got outside) but to prevent them liking jail too much, the regime was very harsh. Sentencing was also very harsh, especially for property crimes.
