 The 11th Earl installed a heraldic chimneypiece in the Dining Hall at Powderham Castle in memory of his grandfather Reginald Courtenay (1741-1803), Bishop of Exeter from 1797 to 1803, and of his parents.The Dining Hall was built by his father the 10th Earl between 1847 and his death in 1859 and the 11th Earl completed the internal decorations in 1860 including the linen-fold panelling containing several dozen ancestral heraldic shields.It is copied from the mediaeval chimneypiece in the Bishop's Palace, Exeter, installed c. 1485 by Peter Courtenay (d.1492) Bishop of Exeter, a younger son of Sir Philip Courtenay (1404-1463) of Powderham.
