1. The history of York stretches back to Roman times. Many buildings have remained more or less
unchanged for centuries. With its ancient wooden houses and narrow winding streets, the
whole city gives off an atmosphere of history. York has been called 'the City of churches' for
there are no fewer than 17 pre-Reformation churches within the city walls. The pride of York is
the huge and magnificent Minster which towers over the whole city.
2. The white cliffs of Dover are familiar to millions of travellers. Dover, the gateway to Britain, is
the busiest ferry port in Europe. On a fine day, the harbour offers excellent walks. Particularly
recommended is the Prince of Wales Pier at the end of which you will find a viewing place with
a splendid outlook over the entire port, the white cliffs and Dover Castle.
3. Portsmouth, a historic military city, is celebrating its 800
,h anniversary. Apart from special
events such as military displays and parades, there is always something to do in Portsmouth.
You can visit historic ships, explore under the sea in the Underwater World, enjoy the yearround Resort Centre — the possibilities are endless, including the luxury cruise to the beautiful
Isle of Wight.
4. Oxford has a timeless beauty which is found at every twist and turn of this ancient university
city: in the soft golden stone of the college buildings and the peaceful gardens. There is so
much to see and do in Oxford. Get a bird's eye panorama of the whole city from the top of St
Mary's. And then there are the shops. The Gallery at Gloucester Green has a busy cosmopolitan
atmosphere, with shops, street cafes and street entertainers.
5. For six days every July, Llangollen becomes the cultural centre of the world, attracting choirs,
musicians, folk singers and dancers from all continents. Over 40 different countries are
represented with colourful national costumes, taking part in daily competitions and performing
in evening concerts. Llangolen is also a centre for outdoor clothing and equipment for climbing,
walking, mountain biking and camping
