Dating to at least the early 13th century, St Ismael's Church, the parish church of Uzmaston, is dedicated to the son of Budic, King of Armorica (France). St Ismael returned to Dyfyd with his brothers (where they previously lived in exile with their father) and became a disciple of St. David. Upon the death of St. David, St. Ismael was consecrated Bishop by his uncle St. Teilo.
In 1230, Uzmaston Church was one of those granted to Wizo the Fleming and his son and grandson (both named Walter) to the Knights of St. John of Jerusalem at Slebech.
The church was virtually rebuilt in 1870-73; renovated in 1991-92; and further restored in 1999.
