Slwch Tump

Slwch Tump is an Iron Age hillfort near Brecon in Powys, Wales. It sits on a hill made of sandstone, 246 metres above sea level, about 1.3 kilometres east of where the Rivers Usk and Honddu meet. A public footpath leads to the site from Slwch Lane, winding around the old ramparts. The fort is smaller and less regular than nearby Pen-y-crug, roughly rectangular and enclosed by a single rampart. In the 19th century, Samuel Lewis noted its defences included a double ditch, now mostly worn away. Hedgerows and trees partly hide its shape today, and old quarries for building stone can still be seen inside the enclosure. The hillfort is linked to the legend of Saint Eluned, one of the daughters of a 5th-century king. According to the story, she refused a pagan prince’s proposal and fled to Slwch Tump, where she built a small cell. When the prince caught her there, he beheaded her with his sword. A spring appeared at the spot, and her cell became a church that stood until 1698. Before the Reformation, the spring was said to cure illness and perform miracles. The church later fell into ruin, but the site remains tied to her story. Visitors find a quiet hilltop with grassy slopes and scattered trees. The ramparts form low earthworks that curve around the hill, and the old quarries add texture to the ground. The public footpath offers a gentle walk up from Slwch Lane, passing through hedgerows before reaching the fort. From the top, there are views over Brecon and the surrounding valleys. The remains of the church and the spring are no longer visible, but the landscape still tells the story of Eluned’s legend. The site is best visited on clear days when the views stretch far across mid-Wales.
