After his beloved granny the Queen Mum died in 2002, Prince Charles got the tradespeople into her former home and spent £4.6 million of taxpayers’ money reshaping Clarence House to his own design yet the public have to pay to have a look at five official rooms when royal residents are on holidays.

The highlight is the late Queen Mother’s small art collection, including one painting by playwright Noël Coward and others by WS Sickert and Sir James Gunn. The house was originally designed by John Nash in the early 19th century, but – as Prince Charles wasn’t the first royal to call in the decorators – has been modified much since. Admission is by timed tickets, which must be booked in advance; book also for disabled access.
