Cardiff's city centre is in the southern portion of the city just north of Cardiff Bay. It is traditionally centred at the castle, bounded to the north by the historic civic centre, large Bute park arboretum and university buildings, by the River Taff to the west, and by the Valleys and National rail lines to the east and south respectively. Growth is pushing the city centre beyond these boundaries, especially in regard to commercial office and residential provision. In particular, the area south of the original city centre towards and including Cardiff Bay has been almost completely redeveloped.

A unique feature of the city is its friendly local population; you can strike up a conversation with almost anyone you meet and speak as if old friends, whether on the bus or in the queue to buy something in a shop. These brief friendly interactions throughout the day make Cardiff an ideal city for lone travellers. The city has a long history of inter-racial marriages and a thriving gay scene making it one of the most welcoming and tolerant cities in the UK.

Cardiff is popular for location filming; Doctor Who has been made here since 2005, and Casualty since 2011. It also has a rich musical history, being the site of many escapades by the famous bands of the Welsh indie music movement such as Catatonia, Super Furry Animals and the Stereophonics. The stunning St. John the Baptist church, gracing the centre of the city, is food for the soul and nearby the Rummer Tavern pub one of the oldest surviving in the city is food for the spirit. Cardiff is the venue of many football and rugby games due to the state-of-the-art stadiums, and Cardiff International Arena's many events such as Comic Con Wales. The Bay area is rich with bars and restaurants and is home to the famous Wales Millennium Centre where one can see anything from comedy to ballet and opera.

Cardiff is a city of life and learning having a huge student population during term time. Many graduates choose to remain due to the friendly and inclusive nature of the city.

It is possible to walk, bike or ride across Cardiff almost entirely via the parks: the Earl of Bute’s lasting legacy to the people of Cardiff. Summer days see the city parks fill with sun-worshippers and snow days see them fill with people playing and snowball fighting with each other!

Cardiff's history follows its castle, which has been occupied since the Romans created a fort on the river Taff over 2,000 years ago. The name 'Cardiff' may have come from 'Caer' = fort, on the 'Taff'.) The fort's original walls can still be seen highlighted around the base of Cardiff Castle's walls. In Medieval times the castle grew, and a small town spread from its south gate; the Medieval street pattern can still be seen around High Street. In the 15th century, the town was destroyed by the last great Welsh prince, Owain Glyndwr. Successive owners fortified the castle and the town timidly grew until the Industrial Revolution, when the 2nd Marquess of Bute built the Glamorganshire Canal to transport coal from the Welsh valleys through Cardiff's docks.

Combined with the later arrival of the railways, Cardiff's population exploded and the docks grew to become the largest coal-exporting port in the world. At its peak, the price of the world's coal was determined at Cardiff's Coal Exchange and the first ever £1,000,000 cheque was written here in 1901 (equivalent to £124,000,000 in 2020). Cardiff was the third largest port of the British Empire, resulting in Edward VII granting Cardiff city status in 1905. With the rise of the city's fortunes, the Marquis of Bute transformed Cardiff castle into a fairytale gothic palace. He also donated land to build the civic centre which contains the City Hall, National Museum, university and government buildings, all built in elaborate neo-classical Baroque styles out of white Portland stone.

The Marquis also commissioned the architect William Burges to design many public and residential buildings in a distinctive Gothic style - many are still visible in the city centre and the inner suburbs. Wales did not have a de jure capital until 1955, when Cardiff was chosen as the largest city. However, with the post-War decline of coal, the city's docks became increasingly abandoned, and in the 1990s the city's transformation began with the building of a barrage to stop the world's second-largest tidal range from revealing dirty mud flats, and creating what is today Europe's largest waterfront regeneration project.

The Bay today is a mixture of apartments, sport, leisure and culture and its success has also seen a rejuvenation of the city centre, where large-scale pedestrianisation and the massive St David's redevelopment in 2009 have created a vibrant city, combining the best of the old, sitting close to modern architecture and amenities. As for the Castle, it was handed over to the people of Cardiff and is now a major tourist, corporate and cultural attraction, an indication of where the city's future lies.

Cardiff has a strong sporting and cultural presence given that it is the capital city, and therefore plays host to most Welsh sporting events, especially since the opening of the Millennium Stadium in the city centre. One of the city's charms is when it plays host to matches, the city centre atmosphere can be extraordinary, being swelled by 75,000 attendees and thousands of revellers.

Cardiff used to be quite a gritty city with the port and industry playing a huge role — Cardiff's ports were once among the most important in the world. Notable milestones were when Cardiff Bay (sometimes called Tiger Bay) was the first area of modern Britain to be thought of as a multicultural area given the huge part immigrants played in the city's ports. The area is still home to one of the oldest and largest expatriate Somali communities in the world. The world's first 'million-pound' deal was also signed at the Bay's own Coal Exchange building.

The city has moved away from its industrial past, however, and has been transformed by developments such as Cardiff Bay, which now hosts famous and striking landmarks such as the National Assembly for Wales and the spectacular Wales Millennium Centre. Massive investments have also been made throughout other parts of the city, such as the opening of the Millennium Stadium and the massive Saint David's shopping centre.

Cardiff is best to visit during late spring to early autumn as the warm weather adds to the city's pleasures and allows maximum experience of all the sites and areas of the city. Although the city usually benefits from mild weather all year round, like much of Wales it also receives substantial rainfall, especially in winter. Being close to the sea and having a comparatively mild climate compared to other parts of England and Wales it also avoids much of the snowfall seen in other parts of the country in winter.
