ISLE OF MAN. This self-governing part of the British Isles, 33 miles long and 13 miles wide, is situated in the middle of the Irish Sea. It has its own laws and parliament (the world's oldest), it issues its own currency, has its own Celtic language (now rarely heard) and tailless cats, called, like its residents, Manx. Steam railroads and electric streetcars add to a sense of dislocation. The Victorian resort of Douglas may be past its prime - offshore banking is the big business now - but along the south-west coast you will find picturesque ports, sandy beaches and glen-cut cliffs. The magnificent sweep of Douglas Bay, against the background of green hills, has a charm hard to equal anywhere. Douglas was a pioneer in illuminations and at night presents a scene of spectacular beauty, never to be forgotten.
