Royal palace of Werla: The Royal Palace of Werla (German: "Königspfalz Werla") is located near Werlaburgdorf (municipality: Schladen-Werla) in Lower Saxony.  The grounds of the royal palace cover about 20 hectares rising atop Kreuzberg hill, a 17 m high natural plateau overlooking the Oker river.  In the Early Middle Ages the palace was an important place in the Holy Roman Empire, serving as an important base for the Ottonians in the 10th century in particular.  Although it subsequently lost its political significance to the newly established Imperial Palace of Goslar at Rammelsberg, it developed into an independent settlement with a busy industrial quarter.  In the 14th century it fell into ruin and was completely unknown until its rediscovery in the 18th century.  The core fortress in particular was thoroughly excavated in the 20th century.  Excavations carried out since 2007 have brought new understanding to the hitherto largely unexplored outworks.  Since 2010 the palace complex with foundation and enceinte, as well as earthworks, has been partially reconstructed and is now open to the public as the "Archäologie- und Landschaftspark Kaiserpfalz Werla" (Archaeological and Wilderness Park of the Imperial Palace of Werla).

List of British royal residences: This is a list of residences occupied by the British royal family, noting the seasons of the year they are traditionally occupied.  Members of the Royal Family inhabit their range of residences across the United Kingdom.  Some are royal palaces, owned by the Crown and held in trust by the monarch; others are privately owned.  Balmoral Castle and Sandringham House have been inherited as private property for several generations.  Other royal palaces are no longer residences (e.g. the Palace of Westminster, the Palace of Whitehall).  Some remain in irregular use for royal occasions (such as Hillsborough Castle).  The Royal Palaces enjoy certain legal privileges: for example, there is an exemption from levying duty on alcoholic beverages sold in the bars at the Palace of Westminster and there are exemptions from Health and Safety legislation.  According to "Halsbury's Laws of England", it is not possible to arrest a person within the "verges" of a royal palace (though this assertion is contradicted by a memorandum by the Clerk of the House of Commons in respect of the Palace of Westminster), and when a royal palace is used as a residence (regardless of whether the monarch is actually living there at the time), judicial processes cannot be executed within that palace.
