The city holds multiple other places as its crown jewels that you should certainly never miss.

Edinburgh

One of Scotland's most beautiful cities, the capital city of Edinburgh is also one of the UK's most visited destinations. Prevalent for its many well-preserved historic structures, Edinburgh is possibly best known as the home of the majestic Edinburgh Castle. Floating high above the old city on a rocky promontory, among the clouds this 13th-century royal fortification includes highlights such as the famous One O'Clock Salute, held daily at Half Moon Battery; the Scottish Crown Jewels in the Royal Palace; the Scottish National War Memorial; and the famous Stone of Destiny (the Stone of Scone), only returned to Scotland after being held for 700 years in London.

Bath

Although one of the UK's smaller cities, Bath more than makes up for its tiny size with a host of things to see and do. Named after its famous Roman Baths, this lovely city has been luring visitors to its curative waters for more than 2,000 years. Pouring from three hot springs, the water-known to consist of 43 different minerals, hence its curative properties-travels upwards some 3,048 meters at a rate of 275,000 gallons per day, before spilling out at a consistent 46.5 degrees Celsius.

York

One of northern England's most popular tourist destinations, the medieval city of York, long the ecclesiastical capital of the Church of England, boasts one of the country's most magnificent cathedrals. The country's largest medieval church, York Minster can trace its roots back to the spread of Christianity in the 3rd century, although the splendid present Gothic structure was built almost 1,000 years later. Highlights of a tour include the chance to view its 14th-century stained glass windows, plus the richly ornamented interiors of the choir and north transept. Also, worth a visit is the crypt, which contains parts of the original 11th-century church the cathedral now stands on.

Liverpool

Liverpool provides plenty of cultural eagerness of its own, not least because of its connotation with the Beatles. Music fans are drawn here for "Fab Four" related attractions such as The Beatles Story in the renovated Albert Docks area; the famous Cavern Club, where the band made its debut in 1961; as well as the previous homes of John Lennon and Paul McCartney.
