The Luisenstadt Canal, or Luisenstädtischer Kanal, is a 2.3 km long former canal in Berlin, Germany.
 It is named after the Luisenstadt district and ran through today's districts of Kreuzberg and Mitte, linking the Landwehr Canal with the Spree River, and serving a central canal basin known as the Engelbecken or Angel's Pool.
 The canal is named after Queen Louise, the wife of King Friedrich Wilhelm III.
The coat of arms of the Kingdom of the Netherlands was originally adopted in 1815 and later modified in 1907.
 The arms are a composite of the arms of the former Dutch Republic and the arms of the House of Nassau, it features a checkered shield with a lion grasping a sword in one hand and a bundle of arrows in the other and is the heraldic symbol of the monarch (currently King Willem-Alexander) and the country.
 The monarch uses a version of the arms with a mantle (Dutch: "Koninklijk wapen" ) while the government of the Netherlands uses a smaller version without the mantle (cloak) or the pavilion, sometimes even only the shield and crown are used (Dutch: "Rijkswapen" ).
 The current components of the coats of arms were regulated by Queen Wilhelmina in a royal decree of 10 July 1907, affirmed by Queen Juliana in a royal decree of 23 April 1980.
The King Willem-Alexander Canal (Dutch: "Koning Willem-Alexanderkanaal" ), named after King Willem-Alexander of the Netherlands, is a 6 km long canal in the northeastern Netherlands.

Queen Juliana was the Queen of the Kingdom of the Netherlands from 4 September 1948 until her abdication on 30 April 1980.

The South Willem's Canal (Dutch: "Zuid-Willemsvaart", [zœytˈʋɪləmsfaːrt]) is a canal in the southern Netherlands, providing a shortcut in river Meuse between the cities of Maastricht and 's-Hertogenbosch.
 The canal was named after King William I of the Netherlands, with "South" added to avoid confusion with two other canals commissioned by and named after the King: the Willem's Canal near Zwolle and the North Willem's Canal in the province of Groningen.

The Tulip Festival is held in Albany, New York every spring at Washington Park.
 It stems from when Mayor Erastus Corning 2nd got a city ordinance passed declaring the tulip as Albany's official flower on July 1, 1948.
 In addition, he sent a request to Queen Wilhelmina of the Netherlands to name a variety as Albany's tulip.
 On July 11, 1948 her reply was "Her Majesty gladly accepts the invitation to designate a tulip as the official flower of Albany."
 She picked the variety "Orange Wonder", an 18-inch tall tulip that is orange-shaded with a scarlet toward the center, it is a slow-grower and relatively rare.
 The first Tulip Fest was celebrated the next year on May 14, 1949 with opening ceremonies still carried on today as tradition, such as the sweeping of State Street and the crowning of a Tulip Queen.
 In 1997 to commemorate the 50th anniversary of the festival the state of New York designated Albany as the "I Love New York Spring Destination".
 Also for the 50th anniversary a descendant variety of the "Wonder Orange" tulip was found in the Netherlands, and the new variety was named "City of Albany".
 The African-American tradition of Pinksterfest, whose origins are traced back even further to Dutch festivities, was later incorporated into the Tulip Fest.
 Since 1998 the Tulip Fest has included the Mother of the Year award.
