Dubey & Schaldenbrand is a luxury watch company dating back to 1946 and named after founders Georges Dubey and René Schaldenbrand.
 In 1995, the revival of Dubey & Schaldenbrand started as a homage to the past with Cinette Robert deciding to open her vault containing her fabulous old movement collection.
 (During the 1970s and early 1980s, Cinette Robert was one of the few visionaries that toured all manufacturers in order to purchase watch movements and components.
 Recasing each movement according to the era when it was created, the Dubey & Schaldenbrand designs rapidly found a niche with collectors.
 Dubey & Schaldenbrand continues to produce small quantities of automatic and mechanical movement watches.
 The company is located in La Chaux-de-Fonds in Switzerland.

 It was opened by Queen Elizabeth II in 1994 and refurbished in 2012.

The Panagyurishte Treasure (Bulgarian: Панагюрско златно съкровище ) is a Thracian treasure excavated on December 8, 1949, by three brothers who worked together at the region of “Merul” tile factory near the town of Panagyurishte, Bulgaria: Pavel, Petko, and Michail Deikov.
 It consists of a phiale, an amphora and seven rhytons with total weight of 6.164 kg of 24-karat gold.
 All of the objects are richly and skilfully decorated with scenes of Thracian myths, customs and life.
 It is dated from the 4th-3rd centuries BC, and is thought to have been used as a royal ceremonial set by the Thracian king Seuthes III.
 As one of the best known surviving artifacts of Thracian culture, the treasure has been displayed at various museums around the world.
 When not on a tour, the treasure is the centerpiece of the Thracian art collection of the National Museum of History in Sofia.
Temple Bar was the principal ceremonial entrance to the City of London on its western side from the City of Westminster.
 It is situated on the historic royal ceremonial route from the Tower of London to the Palace of Westminster, the two chief residences of the mediaeval English monarchs, and from the Palace of Westminster to St Paul's Cathedral.
 The road east of Temple Bar and within the City is Fleet Street, the road to the west, in Westminster, is The Strand.
 At Temple Bar the Corporation of the City of London formerly erected a barrier to regulate trade into the City.
 The 19th century Royal Courts of Justice are located next to it on its north side, having been moved from Westminster Hall.
 To its south is the Temple Church and the Inner Temple and Middle Temple Inns of Court.
 As the most important entrance to the City of London from Westminster, it was formerly long the custom for the monarch to halt at Temple Bar before entering the City of London, in order for the Lord Mayor to offer the Corporation's pearl-encrusted Sword of State as a token of loyalty.
 The term "Temple Bar" strictly refers to a notional bar or barrier across the route, but is commonly used to refer to the 17th-century ornamental Baroque arched gateway designed by Christopher Wren which spanned the road until its removal in 1878.
 Wren's arch was preserved and was re-erected in 2004 in the City, in Paternoster Square next to St Paul's Cathedral.
Kew Palace is a British royal palace in Kew Gardens on the banks of the Thames up river from London.
 Originally a large complex, few elements of it survive.
 Dating to 1631 but built atop the undercroft of an earlier building, the main survivor is known as the Dutch House.
 Its royal occupation lasted from around 1728 until 1818, with a final short-lived occupation in 1844.
 The Dutch House is Grade I listed, and open to visitors.
 It is cared for by an independent charity, Historic Royal Palaces, which receives no funding from the Government or the Crown.
 Alongside the Dutch House is a part of its 18th-century service wing, whilst nearby are a former housekeeper's cottage, brewhouse and kitchen block – most of these buildings are private, though the kitchens are open to the public.
 These kitchens and Queen Charlotte's Cottage are also run by Historic Royal Palaces.
