Yes, the British Royal Family has significant property ties to Wales, though their footprint has changed recently. For many years, the most prominent residence was Llwynywermod, a sustainable estate near Myddfai in Carmarthenshire, which was purchased by the Duchy of Cornwall in 2007 for the then-Prince Charles. However, after becoming King, he gave up the lease, and it now falls under the control of Prince William as the new Prince of Wales. Additionally, the Royal Family owns various lands through the Crown Estate, which includes parts of the Welsh coastline and seabed. Historically, the family has also used private retreats, and Prince William and Catherine notably lived in a rented farmhouse on Anglesey during the Prince's time as a search-and-rescue pilot, which they frequently cite as a very special place for their family.
