Inside the house there are two sets of early 17th century carvings above the dining room and central hall fireplaces. The dining room carvings are earlier while the carving in the main hall commemorates the successful attack by the Prince of Wales against the army of Randulph, Earl of Chester. Three Englishmen’s heads were presented to the Prince of Wales who, in turn, granted these as the Lloyd ancestor’s coat of arms.
There is an unusual mediaeval carving, of “y-sbûr” at the foot of the staircase. This is reported as having come from another Lloyd family property near Llangynog, Montgomeryshire, and is probably what remains of a sideboard or buffet used to support the provisions of bread or cheese.
The entrance hall of Pentrehobyn incorporates an early oak screen on which the craftsmen’s marks are clearly shown, together with some carved dates. Similar craftsmens’ marks can be seen on the huge oak beams supporting the roof on the second floor, currently used as a TV screening area.
