Cefntilla Court, Llandenny, is a 19th-century country house (with 17th-century origins) in Monmouthshire, Wales, which was substantially rebuilt by Thomas Henry Wyatt, for Richard Somerset, 2nd Baron Raglan. The court is a Grade II* listed building as of 31 January 2011.
Richard Somerset's father, FitzRoy Somerset, 1st Baron Raglan had commanded the British forces during the Crimean War. He died in 1855 and Richard succeeded him, his elder brother having died earlier. One thousand six hundred and twenty-three of the late Lord Raglan's "friends and admirers and comrades", purchased the house and estate as a memorial to him in 1858 and presented it to Richard and his heirs in perpetuity. Richard engaged Thomas Henry Wyatt to undertake complete rebuilding of the court in a Tudor style. The house is built of Old Red Sandstone. The interior retains the original Jacobean hall which has a most "unusual early Renaissance" hall frieze which came from Usk Priory. The frieze was decorated in the 1930s by FitzRoy Somerset, 4th Baron Raglan, the antiquarian and historian of Monmouthshire.
On the death in 2010 of FitzRoy Somerset, 5th Baron Raglan, the court, its estate, and its major contents, were left to a nephew, Henry Van Moyland, of Los Angeles, while the title passed to the 5th Baron's younger brother Geoffrey Somerset, 6th Baron Raglan. Following the resolution of a legal dispute between family members, in 2014, the Raglan collection of military memorabilia from both Waterloo and the Crimea was sold for just over £2 million. In Spring 2015, the house itself was under offer with a guide price of £1.6 million and was sold in June 2015.
Memorials to a number of members of the Raglan branch of the Somerset family can be seen in St John's Church, the parish church of Llandenny.
