I want to know the answer to the following question:
What collection did Queen Mary take an interest in by adding and restoring pieces?
All the background I'm provided with is that "Queen Mary also had many new fixtures and fittings installed, such as the pair of marble Empire-style chimneypieces by Benjamin Vulliamy, dating from 1810, which the Queen had installed in the ground floor Bow Room, the huge low room at the centre of the garden façade.". Is that enough to answer the question?
Answer: no
