The Buckingham:

Buckingham
Palace
has served as the official London residence of Britain's
sovereigns since 1837. It evolved from a town house that was owned
from the beginning of the eighteenth century by the Dukes of
Buckingham. Today it is The Queen's official residence.
The Buckingham
collection was created with this grand palace in mind,
incorporating traditional and modern designs with attention to
detail to create this magnificent and distinctive wrought iron and
glass insert.
