Pavel's travel diary

Look at the map of the British Isles. You can see them in the north-west of mainland Europe. Do you know the names of the two largest islands? This is Great Britain and Ireland. In addition, there are more than five hundred small islands. Together they form the United Kingdom of Great Britain and Northern Ireland, Britain for short. This is where I recently arrived. Since Britain is separated from the continent by the English Channel, I had three options: take a plane or cross it by ferry or train through the Channel Tunnel. I chose the fastest and most popular way to travel and here I was landing at Gatwick Airport, 43 kilometers south of London (as the leaflet I picked up at the information desk said).
I couldn't believe my eyes: magnificent scenery and 2,000 years of history awaited me. Admittedly, this is easier said than done
than done because this island nation consists of four countries: England, Wales, Scotland and Northern Ireland. My first destination was England, as it is the largest and most populous of the four. I have already bought postcards of fairly well-known natural attractions, such as the Rivers Thames and Mersey, the south-east coast, sandy or muddy, with occasional chalk cliffs, the Pennines, which run almost like a ridge across England, and the Lake District,
Of course. To the west of England is Wales. With its own charm, it is home to Mount Snowdon, over 1,000m high, the capital Cardiff, leeks, daffodils and the red dragon as the national symbol of the Welsh country. I can't wait to visit Wales!
If I get the chance to go to the north of England, I will one day be in Scotland and enjoy the highlands and lowlands, the many beautiful rivers and lochs (called lochs), the legendary thistle and heather covering
mountain slopes Maybe I'll finally solve the mystery of the Loch Ness Monster! Hooray! And last but not least - Northern Ireland. The nearest point is only 21 km from Scotland. It is separated from Great Britain by the Irish Sea. It has a border in the south and west with the Republic of Ireland. At its center lies Loch Ney, the UK's largest freshwater lake. The whole island is known for its
a beautiful green area, which is why it is sometimes called the Emerald Isle.
I can't wait to see it all!

A few more facts about Great Britain

You probably know that the official or political name of the country is the United Kingdom of Great Britain and Northern Ireland. However, in the United Nations and the European Parliament, it is usually known by its shorter name: United Kingdom or the abbreviation Great Britain.

We often refer to the country as Britain. In addition, there is also a poetic name for the country, Albion. The geographical name of the country is the British Isles, because the country occupies islands called the British Isles. For this reason, it has a single land border with Ireland and a sea border with France.

Like all other countries, Great Britain has its own symbol - the flag. It is called the Union Flag and also the Union Jack. You may ask me why this name? Then you should know that in 1603, King James I (or Jack for short) of England united England and Scotland. Then in 1801 there was a union with Ireland. Now the flag combines elements of three countries (England, Scotland and Northern Ireland) united under one nation. Wales not represented in flag, because at the time of the appearance of the flag in 1606, Wales was already united with England.
Look at the Union Jack. It is a combination of the three crosses of the country's three patron saints: the red cross of St. George for England on a white background; white diagonal cross of St. Patrick of Ireland on a white background.
As for the national coat of arms of the United Kingdom of Great Britain and Northern Ireland, it shows the union of its four parts.
There are emblems for each part of Great Britain: the emblem of England (three lions on a red background), the emblem of Scotland (a red lion on a yellow background), the emblem of Wales (St David and a daffodil) and the emblem of Northern Ireland (a yellow harp on a blue background). Two emblems of English lions symbolize the leading role of England in this union. The shield is supported by two mythical animals: the English lion and the Scottish unicorn. The emblem is crowned with a crowned lion, a symbol of power and might. In addition, under the emblem there are four plant symbols of the four parts of the country. Do you know them? It is a red rose for England, a wild plant called Thistle for Scotland, a vegetable called leek for Wales and another wild plant called Shamrock for Northern Ireland. In conclusion, I would name the historical colors of parts of Great Britain: England - white; Scotland - Blue; Wales - Red; Northern Ireland - Green.

Sports teams of nations wear these colors.
