Thor Heyerdahl Upper Secondary School was formed in 2004 by the merger of the previously existing upper secondary schools in Larvik:
Farris videregående skole (previously known as
Larvik handelsskole, Larvik business school),
Gloppe skole (previously
Vestfold fylkes husflidskole,
Vestfold handcrafts school),
Kilden videregående skole (previously
Larvik yrkesskole, Larvik vocational school) and
Larvik gymnas (Larvik
gymnasium). The
gymnasium's history goes back to the foundation of
Laurvigs Middelskole (Larvik Middle School) in 1824; the Thor Heyerdahl name was first used in 1994. The
municipality of Larvik bought the
gymnasium building and acquired Ahlefeldtsgate 6, 8 and 10 for 30.3 million
kroner, but did not acquire the Farris or Gloppe school sites. On 17 August 2009 the school's new building opened, uniting all courses on a single campus. The official opening ceremony took place on 18 September. The building was designed by the Danish architecture firm of
schmidt hammer lassen, who won the design competition in January 2006 in collaboration with the SLA landscape architecture firm with a proposal named
Synergy. Construction began in June 2007 with the demolition of the old school; ground was broken for the new building in August. The new building has five storeys in addition to workshops; it is connected to the arena by a first-floor bridge. Interior decoration of the new building was budgeted at approximately 1.8 million kroner, the design scheme being chosen by a jury. The building was nominated for Building of the Year in its class by
Byggeiindustrien. In 2020, Lin Marie Holvik was announced as the school's new
rector. ==Educational offerings and facilities==
