The Isle of Man
In the Irish Sea about 20 miles away from the UK you will find a beautiful island. This is the Isle of Man. The people of the island are called
Manx and they speak the Manx language. The island occupies a mid-point in the Irish Sea and the British Isles - right between England,
Ireland, Scotland and Wales.
The scenery of the Isle is varied. There are ranges of hills with green valleys between them, there are sandy beaches in the north which
contrast with the rocky cliffs along the coasts. The island's only mountain is slightly over 600 metres high. An old legend says that from its top
on clear days you can see six kingdoms: the island itself, Scotland, England, Ireland, Wales and Heaven.
The Isle of Man has the oldest parliament in the world. It is called the Tynwald and it has met regularly since 979. The Tynwald usually meets in
the capital of the country. However, for one day every summer the Manx parliament gathers in a small village to celebrate Tynwald Day. It is
the only day of the year when parliament is held in the open air. On this day government officials read a summary of all the laws that have
been passed during the year in both the English and the Manx languages. There is entertainment before and after the ceremony and it is a
real community event. In addition to that, an open air market is organised and different concerts are held in the evening. At the conclusion,
the Manx national anthem is played and there is a firework display.
Another thing that attracts tourists to the Isle of Man is its rich and unique culture. Any visitor to the island will be particularly fascinated by
the legends, folklore and the ancient traditions that are still kept alive today. Most tourists are happy to participate in the folk programmes.
In Manx mythology, the island's name comes from the name of a Celtic sea god. He ruled the kingdom and protected the land from invaders
by covering the island with mist and thick fog. The island is also reputedly home to fairies who are very special. The Manx fairies are described
as small and human -- like. They wear red caps and green jackets and are naughty and wicked.
There's even a bridge called Fairy Bridge. Those who cross it are advised to say "hello fairies in order to get good fortune. If the person
doesn't greet the fairies, the fairies will become angry with him and may play a nasty trick on him. Some people go further in trying to pay
their respects to the little people. They do not just simply say hello, they also leave messages and gifts at the side of the road.
If you love reading about King Arthur and his knights, then a must-see place is Peel Castle. It was constructed in the 11th century by the
Vikings and has a fascinating history. It is believed that Peel Castle was the location of Avalon - the legendary island where King Arthur's
sword was made and where King Arthur was taken after being wounded
