Lohja is a bilingual municipality with Finnish and Swedish as its official languages. The population consists of 90% Finnish speakers, 3% Swedish speakers, and 6% speakers of other languages. City's bilingual slogan is: Järvikaupunki – Insjöstaden which translates to "Lake city".
The landscape of Lohja is characterized by manors and gardens. Its area is divided by the Lohja ridge, which forms a watershed for the largest lake system in Uusimaa, Lake Lohja (Lohjanjärvi); mostly that's why Lohja is also referred to as "Lake City" (järvikaupunki). The medieval Church of St. Lawrence is the architectural highlight of downtown Lohja, which also includes a heterogeneous mix of buildings mostly dating from the 1960s onwards. The Lohja library, which was opened in 2005, is a distinctly modern building placed in the very centre of the city.
Lohja has been a focal point for the population and economy of western Uusimaa since the early 14th century. It was renowned as a trading centre in the Middle Ages. The local inhabitants were among the pioneers of the Finnish mining and construction material industries. Lohja has long-established traditions in horticulture and especially in market gardening. These traditions are represented by the symbols of present-day Lohja: limestone and an apple.
