In pictures: Cardiff celebrates a century Have your say on centenary

Cardiff, then a fast-growing coal port, was made a city on 28 October, 1905.

The city was bombed in World War Two and suffered from the decline in industry which followed, but the city has undergone major regeneration in the past decade.

Events including an RAF flypast and the cutting of a giant birthday cake marked the centenary on Friday.

A series of events were held across Cardiff to mark the centenary.

Cardiff Castle's grounds were open for the day, and most leisure centre facilities were available for 50p.

Street entertainment in the city centre and a free concert at St David's Hall were among the events laid on as part of Friday's celebrations.

Three RAF Hawks flew past after a dedication by the Lord Mayor, Freda Salway, of a plaque marking the start of work on Cardiff International Pool, at the city's planned �1.2bn International Sports Village.

The grounds of Cardiff Castle are open for the day, with tours of the castle.

In the afternoon, Ms Salway used the city's ceremonial sword to cut a cake made to mark the 100th birthday.

The city's electronic road signs marked the centenary throughout the day by flashing up the message "Cardiff 100 years a city today". A celebratory message was also displayed on the big screen in Queen Street.

Cardiff Council asked people around the world to send their greetings via a free postcard which people were invited to send to friends and family.

The card displayed a celebratory image of fireworks over Roald Dahl Plass in Cardiff Bay. On the reverse was a message which explained the day's significance and invited the reader to log onto a webpage to leave their birthday wishes.
