St Teilo’s Church, now lovingly re-erected within the open-air precinct of St Fagan’s Museum of Welsh Life, is a remarkable testament to Wales’s medieval and 16th century heritage. Originally constructed in the early 16th century, this humble parish church was painstakingly dismantled, transported, and restored to its former glory — not least its dazzling wall paintings, which have been carefully recreated with scholarly precision. These vivid murals, brought back to life through meticulous craftsmanship, offer visitors a rare window into the devotional art and storytelling of the late medieval period. Stepping inside St Teilo’s, you’re transported back half a millennium, immersed in a world where faith, community, and artistic expression converged on plastered walls that still speak with vibrant colour and enduring power.
