City Sets

Lego City is a theme under which Lego building sets are released. As the name suggests, Lego City sets are based on city life, with the models depicting city and emergency services (such as police and fire), airport, train, construction, and civilian services.
The History of LEGO City

The City theme traces its origins to Lego Town, a theme introduced with the first minifigures in 1978. Since then, town-based models have been marketed under the names Legoland Town, Town Junior, City Center, and World City before the current incarnation was started in 2005. The first set introduced under the City name was 10159 Airport (a reissue of the 1994 airport set Century Skyway, with some minor part differences).

Since its introduction, different subthemes under the City banner were used to tie together related sets, such as Police, Fire, Trains, Transportation, and Construction. During the Christmas season, a City-themed Advent Calendar set is sold through the online Lego Shop and at retailers.
