The courthouse is over 400 years old. Although alterations were made in the 19th century, its original character remains the same. Today cases are heard once a year.

Throughout the centuries the courthouse has witnessed various cases from petty misdemeanours to murder.

In 1768, Hugh Jones stole eight cheeses and a quarter of beef. He was publicly whipped in four towns on the island.

In 1910, William Murphy was sentenced to death for killing his mistress on Christmas Day. He was hanged in Caernarfon.

This place even today makes you want to stand in the dock and shout "not guilty!"
