Your adventure begins at the Animal Wall, a distinctive feature of the Cardiff Castle Historic Site. Built between 1901 and 1930, this wall was originally intended to feature 58 sculpted animals, but only 9 were completed, including a lynx and a lion. These statues, commissioned by the 3rd Marquess of Bute and his family, symbolize the eccentricity and artistic taste of the Victorian era in Cardiff. Here, the first fragment of the plan awaits you, hidden in the details of one of these stone creatures, initiating you into the mysteries of Welsh heritage.
Then, enter the grounds of Cardiff Castle, a building whose foundations date back to 1081, when the Normans built a motte-and-bailey castle there. This historic site, in the heart of Cardiff, was profoundly transformed in the 19th century by John Crichton-Stuart, 3rd Marquess of Bute, in collaboration with architect William Burges. The Roman Wall, a remnant of Roman occupation, and the Clock Tower, lavishly restored, bear witness to the layering of eras. Your quest will lead you to decipher engraved symbols that will reveal the Marquess's secret intentions for the castle's expansion.
The path then leads you to the medieval heart of the castle, the Motte and Bailey, the original fort built by the Normans. This elevated mound offers a strategic view of Bute Park Green Space and the River Taff, 40 miles long, which borders the park. In 1899, the Gorsedd Stone Circle was erected there for the National Eisteddfod of Wales, marking the link between ancient history and modern Welsh culture. Here you will discover a key clue, related to the building materials the Marquess of Bute had envisioned for his projects.
As you walk along the River Taff, you will cross historic bridges near the castle, evidence of Cardiff's urban development. Here stands the Statue of the 3rd Marquess of Bute, a bronze work by Bertram MacKennal erected in 1921, approximately 6 meters high. This statue, erected long after John Patrick Crichton-Stuart's death in 1900, highlights the lasting impact of his vision on the city. One of the details of this sculpture holds a message that only a trained eye, like yours, can decipher, revealing part of the Marquess's enigma.
Your journey concludes at the North Gate of Cardiff Castle, a 12th-century medieval gate that underwent Victorian restoration in the 19th century. This gate, an integral part of the Norman fortifications, symbolizes the persistence of history through the ages. The final clues, hidden in the coats of arms or architectural motifs, will allow you to reconstruct the entirety of the Marquess of Bute's plans. This interactive tour of Cardiff will have taken you through the Victorian Heritage of Wales, a true GPS scavenger hunt through the history of Cardiff.
