Suddenly, a hush falls over the crowd as history is made – the world's first million-pound coal deal is struck right here in Cardiff! This landmark transaction cemented Cardiff's status as a global powerhouse in the coal trade. At its peak, Cardiff was exporting more coal than any other port in the world, earning it the nickname "Coal Metropolis". The Coal Exchange building still stands today in Cardiff Bay, a testament to the city's industrial heritage.

The Birthplace of Roald Dahl Calling all bookworms and dreamers! Did you know that the master of whimsical tales and childhood fantasies, Roald Dahl, was born right here in Cardiff? That's right, the creator of Charlie and the Chocolate Factory, Matilda, and The BFG took his first breath in the Llandaff area of Cardiff in 1916. Dahl's Welsh roots played a significant role in shaping his imagination. In fact, the sweet shop featured in his autobiography "Boy" was inspired by a real confectionery on Llandaff High Street. Today, you can follow in Dahl's footsteps on the Roald Dahl Trail, which includes his birthplace, the sweet shop that sparked his creativity, and the church where he was christened.

The Castle with a Wartime Secret Cardiff Castle is a must-see for any visitor, but did you know it harbors a fascinating World War II secret? Beneath its walls lie a network of tunnels that served as air-raid shelters during the Blitz. But these weren't just any old bomb shelters – they could accommodate up to 1,800 people and were equipped with dormitories, canteens, and even a hospital! Today, you can explore a section of these tunnels that's been reconstructed to give visitors a glimpse into wartime life. Walking through these corridors, you can almost hear the echoes of the past – the sirens, the nervous chatter, the relief of safety.

Originally designed by architect William Burges and sculpted by Thomas Nicholls, the wall features 15 animals including a hyena, a seal, a bear, and even a pair of apes. But here's the kicker – in the 1930s, the animals' glass eyes were replaced with electric ones that would light up at night! While the electric eyes are long gone, the charm of the Animal Wall remains. It's a perfect blend of history, art, and whimsy that you won't find anywhere else.
