Tournament Park is a park and athletics venue in Pasadena, California, currently maintained by the California Institute of Technology.
 It was simply known as the "town lot" before being renamed Tournament Park in 1900.
 Tournament Park gets its name from the Tournament of Roses, and it served as a venue in the early 20th century for events associated with the Tournament, such as chariot races, ostrich races, and even a race between a camel and an elephant.
 It is best known for being the site of the first Rose Bowl Game in 1902, and the second to eighth Rose Bowl Games from 1916 to 1922 before the Rose Bowl opened in 1923.
 Its capacity at the time was 43,000 people, many of which were in temporary wooden bleachers that the city deemed unsafe, thus necessitating the construction of the Rose Bowl.
 Besides hosting Tournament of Roses events, the venue also hosted the Southern California Horse Show Association's annual horse show in the early 20th century.
 Tournament Park hosted a handful of USC football games in the 1910s and 1920s prior to the construction of Los Angeles Memorial Coliseum
Saltwood Castle is a castle in Saltwood village, one mile (2 km) north of Hythe, Kent, England.
 Of 11th century origin, the castle was expanded in the 13th and 14th centuries.
 After the Norman Conquest, the castle was appropriated by the Archbishop of Canterbury Lanfranc and remained the property of the archbishops, with some interruptions, until 1540, when Thomas Cranmer was compelled to cede it to Henry VIII.
 The castle is reputed to have been the meeting place of the four knights who carried out the assassination of Thomas Becket in 1170.
 By the 19th century, it was "largely ruinous" and restorations to make portions of the castle habitable were carried out in the 1880s and 1930s.
 In the late 19th century, the castle was bought by an ancestor of Bill Deedes, the journalist and politician, who grew up there.
 In the 20th century, it was sold to Sir Martin Conway who commissioned Philip Tilden to undertake a restoration.
 In 1953, the castle was bought by the art historian Kenneth Clark (1903–1983), and then became the home of his son, the politician and diarist, Alan Clark (1928–1999).
 It remains the private home of his widow, Jane Clark.
 The castle is a Grade I listed building.

Sămănătorul or Semănătorul (] , Romanian for "The Sower") was a literary and political magazine published in Romania between 1901 and 1910.
 Founded by poets Alexandru Vlahuță and George Coșbuc, it is primarily remembered as a tribune for early 20th century traditionalism, neoromanticism and ethnic nationalism.
 The magazine's ideology, commonly known as "Sămănătorism" or "Semănătorism", was articulated after 1905, when historian and literary theorist Nicolae Iorga became editor in chief.
 While its populism, critique of capitalism and emphasis on peasant society separated it from other conservative groups, "Sămănătorul" shared views with its main conservative predecessor, the "Junimea" society, particularly in expressing reserve toward Westernization.
 In parallel, its right-wing agenda made it stand in contrast to the Poporanists, a Romanian populist faction whose socialist-inspired ideology also opposed rapid urbanization, but there was a significant overlap in membership between the two groups.
 "Sămănătorul"' s relationship with the dominant National Liberal Party was equally ambiguous, ranging from an alliance between "Sămănătorul" and National Liberal politician Spiru Haret to Iorga's explicit condemnation of 20th century Romanian liberalism.
