In fact, I was most impressed by what I have seen inside the palace – the paintings and the furniture.
It features how the royal family has lived.
Here are a couple of photos showing the rooms within the palace.
This is how the Palace is introduced in Wikipedia:
Rundāle Palace , formerly also Ruhenthal and Ruhendahl is one of the two major baroque palaces built for the Dukes of Courland in what is now Latvia, the other being Jelgava Palace. The palace was built in two periods, from 1736 until 1740 and from 1764 until 1768. It is situated at Pilsrundāle, 12 km west of Bauska.
