The place of government , but with extensive royal apartments. The Westminster Hall which we see today was extensively remodelled by Richard II but was founded on the same outer walls. In the earlier building the roof was supported by two rows of internal pillars. it is all which is left of the Palace of the 14th century the rest of which was removed by two disastrous fires in 1512 and 1384.

One of the fascinating snippets is that most rooms could be accessed both from the public corridors, which might in themselves be very private, or from a totally seperate set of royal corridors. This facilitated both affairs of state and other very different affairs.
