The marvellous Istana Besar, once the Johor royal family’s principal palace, was built in Victorian style by Anglophile sultan Abu Bakar in 1866. It was opened as a museum to the public in 1990 and displays the incredible wealth of the sultans. It's now the finest museum of its kind in Malaysia, and the 53-hectare palace grounds (free entry) are beautifully manicured.
At the time of research the museum was getting an extensive remodelling, with plans to reopen in 2016.
